72-10-04 R2 BEECH: Amendment 39-1445 as amended by Amendment 39-1888 is further amended by Amendment 39-4385. Applies to Models 99, 99A, A99, A99A and B99 airplanes, except airplanes equipped with a hydraulic-operated landing gear per Beech Kit No. 99-8010-1.

A) At intervals not exceeding 100 hours' time in service inspect forward and rear nose gear chains for wear and tension and lubricate the chains.

B) At intervals not exceeding 2500 landings, inspect each landing gear actuator for jackscrew end play and integrity of mounting.

C) At intervals not exceeding 1000 hours' time in service, lubricate each landing gear actuator.

D) If an unairworthy condition is found during action outlined above, replace or repair components as necessary to correct the condition, prior to further flight, except that the aircraft may be flown in accordance with FAR 21.197 to a base where the repair or replacement can be made.

Upon request of an operator, an FAA maintenance inspector, subject to approval of the Chief, Engineering and Manufacturing Branch, FAA, Central Region, may adjust inspection and replacement intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator.

NOTE: Notwithstanding the installation of the hydraulic landing gear retraction systems per Beech Kit No. 99-8010-1, normal maintenance practices with respect to the landing gear system prescribed in the Beech 99 Airliner Shop Manual (Part No. 99-590015B revised March 1972, or any later revision) should be followed.
