 a fire-extinguishing system that is in a designated fire zone must be made of
 fireproof materials.
   (b) Connections that are subject to relative motion between components of
 the airplane must be made of flexible materials that are at least fire-
 resistant and be located so as to minimize the probability of failure.






 Sec. 125.171  Fire-detector systems.

   Enough quick-acting fire detectors must be provided in each designated fire
 zone to assure the detection of any fire that may occur in that zone.






 Sec. 125.173  Fire detectors.

   Fire detectors must be made and installed in a manner that assures their
 ability to resist, without failure, all vibration, inertia, and other loads
 to which they may be normally subjected. Fire detectors must be unaffected by
 exposure to fumes, oil, water, or other fluids that may be present.






 Sec. 125.175  Protection of other airplane components against fire.

   (a) Except as provided in paragraph (b) of this section, all airplane
 surfaces aft of the nacelles in the area of one nacelle diameter on both
 sides of the nacelle centerline must be made of material that is at least
 fire resistant.
   (b) Paragraph (a) of this section does not apply to tail surfaces lying
 behind nacelles unless the dimensional configuration of the airplane is such
 that the tail surfaces could be affected readily by heat, flames, or sparks
 emanating from a designated fire zone or from the engine from a designated
 fire zone or from the engine compartment of any nacelle.






 Sec. 125.177  Control of engine rotation.

   (a) Except as provided in paragraph (b) of this section, each airplane must
 have a means of individually stopping and restarting the rotation of any
 engine in flight.

 rotation need be provided only if the Administrator finds that rotation could
 jeopardize the safety of the airplane.






 Sec. 125.179  Fuel system independence.

   (a) Each airplane fuel system must be arranged so that the failure of any
 one component does not result in the irrecoverable loss of power of more than
 one engine.
   (b) A separate fuel tank need not be provided for each engine if the
 certificate holder shows that the fuel system incorporates features that
 provide equivalent safety.






 Sec. 125.181  Induction system ice prevention.

   A means for preventing the malfunctioning of each engine due to ice
 accumulation in the engine air induction system must be provided for each
 airplane.






 Sec. 125.183  Carriage of cargo in passenger compartments.

   (a) Except as provided in paragraph (b) or (c) of this section, no
 certificate holder may carry cargo in the passenger compartment of an
 airplane.
   (b) Cargo may be carried aft of the foremost seated passengers if it is
 carried in an approved cargo bin that meets the following requirements:
   (1) The bin must withstand the load factors and emergency landing
 conditions applicable to the passenger seats of the airplane in which the bin
 is installed, multiplied by a factor of 1.15, using the combined weight of
 the bin and the maximum weight of cargo that may be carried in the bin.
   (2) The maximum weight of cargo that the bin is approved to carry and any
 instructions necessary to ensure proper weight distribution within the bin
 must be conspicuously marked on the bin.
   (3) The bin may not impose any load on the floor or other structure of the

 that may be carried in the bin.
   (5) The bin may not be installed in a position that restricts access to or
 use of any required emergency exit, or of the aisle in the passenger
 compartment.
   (6) The bin must be fully enclosed and made of material that is at least
 flame-resistant.
   (7) Suitable safeguards must be provided within the bin to prevent the
 cargo from shifting under emergency landing conditions.
   (8) The bin may not be installed in a position that obscures any
 passenger's view of the "seat belt" sign, "no smoking" sign, or any required
 exit sign, unless an auxiliary sign or other approved means for proper
 notification of the passenger is provided.
   (c) All cargo may be carried forward of the foremost seated passengers and
 carry-on baggage may be carried alongside the foremost seated passengers if
 the cargo (including carry-on baggage) is carried either in approved bins as
 specified in paragraph (b) of this section or in accordance with the
 following:
   (1) It is properly secured by a safety belt or other tie down having enough
 strength to eliminate the possibility of shifting under all normally
 anticipated flight and ground conditions.
   (2) It is packaged or covered in a manner to avoid possible injury to
 passengers.
   (3) It does not impose any load on seats or the floor structure that
 exceeds the load limitation for those components.

 sign, "no smoking" sign, or required exit sign, unless an auxiliary sign or
 other approved means for proper notification of the passenger is provided.






 Sec. 125.185  Carriage of cargo in cargo compartments.

   When cargo is carried in cargo compartments that are designed to require
 the physical entry of a crewmember to extinguish any fire that may occur
 during flight, the cargo must be loaded so as to allow a crewmember to
 effectively reach all parts of the compartment with the contents of a hand-
 held fire extinguisher.






 Sec. 125.187  Landing gear: Aural warning device.

   (a) Except for airplanes that comply with the requirements of Sec. 25.729
 of this chapter on or after January 6, 1992, each airplane must have a
 landing gear aural warning device that functions continuously under the
 following conditions:
   (1) For airplanes with an established approach wing-flap position, whenever
 the wing flaps are extended beyond the maximum certificated approach climb
 configuration position in the Airplane Flight Manual and the landing gear is

 *****************************************************************************


 59 FR 1780, No. 8, Jan. 12, 1994

   SUMMARY: This amendment revises the regulations concerning first aid kits
 required on board air carrier, air taxi, and commercial aircraft to remove
 the burn compound from the list of items required for the kits. This
 amendment responds to a petition from Air Transport Association, supported by
 the American Red Cross, that the burn compound be removed from the kits since
 the use of ice or cold water is the preferred treatment for minor burns. This
 amendment will relieve affected operators from the expense of having to
 periodically replace an item in the first aid kits that is not needed.

   (1) Takeoffs may be made with frost adhering to the wings, or stabilizing
 or control surfaces, if the frost has been polished to make it smooth.
   (2) Takeoffs may be made with frost under the wing in the area of the fuel
 tanks if authorized by the Administrator.
   (b) No certificate holder may authorize an airplane to take off and no
 pilot may take off an airplane any time conditions are such that frost, ice,
 or snow may reasonably be expected to adhere to the airplane unless the pilot
 has completed the testing required under Sec. 125.287(a)(9) and unless one of
 the following requirements is met:
   (1) A pretakeoff contamination check, that has been established by the
 certificate holder and approved by the Administrator for the specific
 airplane type, has been completed within 5 minutes prior to beginning
 takeoff. A pretakeoff contamination check is a check to make sure the wings
 and control surfaces are free of frost, ice, or snow.
   (2) The certificate holder has an approved alternative procedure and under
 that procedure the airplane is determined to be free of frost, ice, or snow.
   (3) The certificate holder has an approved deicing/anti-icing program that
 complies with Sec. 121.629(c) of this chapter and the takeoff complies with

 *****************************************************************************


 58 FR 69620, No. 249, Dec. 30, 1993

 SUMMARY: This interim final rule requires part 125 certificate holders to
 provide pilot testing on conducting operations in ground icing conditions,
 part 135 certificate holders to provide pilot training on conducting
 operations in ground icing conditions, and part 125 and 135 certificate
 holders to check airplanes for contamination (i.e., frost, ice, or snow)
 prior to takeoff when ground icing conditions exist. This rule is necessary
 because accident statistics and experience indicate the importance of
 effectively determining whether the airplane's wings and control surfaces are
 free of all frost, ice, or snow prior to beginning a takeoff. The rule is
 intended to provide an added level of safety to flight operations in ground
 icing conditions under parts 125 and 135.

 DATES: This interim final rule is effective January 31, 1994.

 carrying operations unless approved airborne weather radar equipment is
 installed in the airplane.
   (b) No person may begin a flight under IFR or night VFR conditions when
 current weather reports indicate that thunderstorms, or other potentially
 hazardous weather conditions that can be detected with airborne weather radar
 equipment, may reasonably be expected along the route to be flown, unless the
 airborne weather radar equipment required by paragraph (a) of this section is
 in satisfactory operating condition.
   (c) If the airborne weather radar equipment becomes inoperative en route,
 the airplane must be operated under the instructions and procedures specified
 for that event in the manual required by Sec. 125.71.
   (d) This section does not apply to airplanes used solely within the State
 of Hawaii, within the State of Alaska, within that part of Canada west of
 longitude 130 degrees W, between latitude 70 degrees N, and latitude 53
 degrees N, or during any training, test, or ferry flight.
   (e) Without regard to any other provision of this part, an alternate
 electrical power supply is not required for airborne weather radar equipment.






 Sec. 125.224   Traffic Alert and Collision Avoidance System.

   (a) After December 30, 1993, no person may operate a large airplane that
 has a passenger seating configuration, excluding any pilot seat, of more than
 30 seats unless it is equipped with an approved TCAS II traffic alert and
 collision avoidance system and the appropriate class of Mode S transponder.
   (b) The manual required by Sec. 125.71 of this part shall contain the
 following information on the TCAS II system required by this section.
   (1) Appropriate procedures for--
   (i) The operation of the equipment; and

 55 FR 13242, No. 68, Apr. 9, 1990

   SUMMARY: This rule revises the schedule for installing Traffic Alert and
 Collision Avoidance Systems (TCAS II) on airplanes with more than 30
 passenger seats. The TCAS II system will provide a collision avoidance
 capability that operates independently of the ground-based Air Traffic
 Control (ATC) system and in areas where there is no ATC coverage. Congress
 recently passed legislation permitting an extension of the schedule. This
 action implements the legislation, reduces the prospect that carriers will
 divert critical maintenance and modification resources away from other safety
 programs to meet the TCAS II schedule, and allows the FAA to evaluate the
 operation of TCAS II in the total ATC environment.

   EFFECTIVE DATE: May 9, 1990.

 58 FR 69620, No. 249, Dec. 30, 1993

 SUMMARY: This interim final rule requires part 125 certificate holders to
 provide pilot testing on conducting operations in ground icing conditions,
 part 135 certificate holders to provide pilot training on conducting
 operations in ground icing conditions, and part 125 and 135 certificate
 holders to check airplanes for contamination (i.e., frost, ice, or snow)
 prior to takeoff when ground icing conditions exist. This rule is necessary
 because accident statistics and experience indicate the importance of
 effectively determining whether the airplane's wings and control surfaces are
 free of all frost, ice, or snow prior to beginning a takeoff. The rule is
 intended to provide an added level of safety to flight operations in ground
 icing conditions under parts 125 and 135.

 DATES: This interim final rule is effective January 31, 1994.

 a pilot in command of an airplane under IFR unless, since the beginning of
 the sixth calendar month before that service, that person has passed an
 instrument proficiency check and the Administrator or an authorized check
 airman has so certified in a letter of competency.
   (b) No pilot may use any type of precision instrument approach procedure
 under IFR unless, since the beginning of the sixth calendar month before that
 use, the pilot has satisfactorily demonstrated that type of approach
 procedure and has been issued a letter of competency under paragraph (g) of
 this section. No pilot may use any type of nonprecision approach procedure
 under IFR unless, since the beginning of the sixth calendar month before that
 use, the pilot has satisfactorily demonstrated either that type of approach
 procedure or any other two different types of nonprecision approach
 procedures and has been issued a letter of competency under paragraph (g) of
 this section. The instrument approach procedure or procedures must include at
 least one straight-in approach, one circling approach, and one missed
 approach. Each type of approach procedure demonstrated must be conducted to
 published minimums for that procedure.
   (c) The instrument proficiency check required by paragraph (a) of this

 considered to have completed the test or check in the calendar month in which
 it is required.
   (b) If a pilot being checked under this subpart fails any of the required
 maneuvers, the person giving the check may give additional training to the
 pilot during the course of the check. In addition to repeating the maneuvers
 failed, the person giving the check may require the pilot being checked to
 repeat any other maneuvers that are necessary to determine the pilot's
 proficiency. If the pilot being checked is unable to demonstrate satisfactory
 performance to the person conducting the check, the certificate holder may
 not use the pilot, nor may the pilot serve, in the capacity for which the
 pilot is being checked in operations under this part until the pilot has
 satisfactorily completed the check.






 Sec. 125.295   Check airman authorization: Application and issue.

   Each certificate holder desiring FAA approval of a check airman shall
 submit a request in writing to the FAA Flight Standards district office
 charged with the overall inspection of the certificate holder. The
 Administrator may issue a letter of authority to each check airman if that
 airman passes the appropriate oral and flight test. The letter of authority
 lists the tests and checks in this part that the check airman is qualified to
 give, and the category, class and type airplane, where appropriate, for which
 the check airman is qualified.






 Sec. 125.297   Approval of airplane simulators and other training devices.
