## The airworthiness directive

83-08-05 BEECH: Amendment 39-4637. Applies to Models 60, A60, and B60 (S/Ns P-4 through P-577, P-579 through P-587, P-589, and P-592) airplanes, having optional air conditioning systems installed, 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 loss of power or inflight fires caused by a loose air conditioner compressor clutch pulley contacting an adjacent fuel line, accomplish the following:

a) Modify the air conditioner compressor installation by incorporating the appropriate Beech Kit No. 60-5026-1S or No. 60-5026-3S as identified by criteria in Beechcraft Class I Service Instructions No. 1236 or;

b) Deactivate the air conditioner system in accordance with the following:

  (1) Remove the air conditioner compressor belt.

  (2) Pull and block the air conditioning circuit breaker so that it cannot be inadvertently reset.

  (3) Install a permanent placard in full view of the pilot near the cabin comfort control which reads as follows:

"AIR CONDITIONER DEACTIVATED."

c) Airplanes may be flown in accordance with FAR 21.197 to a location where the AD may be accomplished.

d) An equivalent means of compliance with this AD may be used, if approved, by the Manager, Wichita Aircraft Certification Office, Room 238, Terminal Building 2299, Mid- Continent Airport, Wichita, Kansas 67209; telephone (316) 269-7000.

This amendment becomes effective on May 3, 1983.
