ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 86-24-09 BEECH AIRCRAFT CORPORATION: Amendment 39-5482. Applies to Model B-100 (all serial numbers) airplanes certificated in any category. Compliance: Required within the next 50 hours time-in-service after the effective date of this AD, unless already accomplished. To prevent engine flameout when in or departing an icing environment, accomplish the following: (a) Revise the airplane Pilot's Operating Handbook and Airplane Flight Manual (POH/AFM) by inserting Appendix 1 of this AD in the "LIMITATIONS" section of the POH/AFM. Appendix 1 procedures supersede any other POH/AFM procedures which may be contradictory. (b) The requirements of paragraph (a) of this AD may be accomplished by the holder of a pilot certificate issued under Part 61 of the Federal Aviation Regulations on any airplane owned or operated by him. The person accomplishing these actions must make the appropriate aircraft maintenance record entry as prescribed by FAR 91.173. (c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (d) An equivalent method of compliance with this AD, if used, must be approved by contacting the Manager, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209; Telephone (316) 946-4400. All persons affected by this directive may obtain copies of the document referred to herein upon request to GTEC, P.O. Box 5217, Phoenix, Arizona 85010; Telephone (602) 231- 1000; or Beech Aircraft Corporation, P.O. Box 85, Wichita, Kansas 67201; Telephone (316) 681- 9111; or FAA, Office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106. This amendment becomes effective on December 15, 1986. APPENDIX 1 Supplement to the POH/AFM Beech Model B-100 Airplanes "The MAN FUEL/IGN switches shall be selected to ON during all operations in actual or potential icing conditions described herein: (1) During takeoff and climb out in actual or potential icing conditions. *(2) When ice is visible on, or shedding from propeller(s), spinner(s), or leading edge(s). *(3) Before selecting ANTI-ICE, when ice has accumulated. (4) Immediately, any time engine flameout occurs as a possible result of ice ingestion. (5) During approach and landing while in or shortly following flight in actual or potential icing conditions. * NOTE: If icing conditions are entered in flight without the engine anti-icing system having been selected, switch one ENGINE system to the ANTI-ICE ON position. If the engine runs satisfactorily, switch the second ENGINE system to the ANTI-ICE ON position and check that the second engine continues to run satisfactorily. CAUTION Flight in actual or potential icing conditions will be limited by duty cycle of the ignition system. Ignition system time limits must be observed to prevent exceeding duty cycle times. Operator should verify these limits for his particular installation. For the purpose of this supplement, the following definition applies: "Potential icing conditions in precipitation or visible moisture meteorological conditions: (1) Begin when the OAT is plus 5 degrees C (plus 41 degrees F) or colder, and (2) End when the OAT is plus 10 degrees C (plus 50 degrees F) or warmer." The procedures and conditions described in this appendix supersede any other POH/AFM procedures and conditions which may be contradictory. FOOTER:
