59-08-01 BEECH: Applies to Models A35, B35, C35, Serial Numbers D-1501 Through D-2800.

Compliance required prior to July 1, 1959.

Several cases of landing gear actuation failure have been attributed to malfunctioning of the landing gear limit switches due to oil accumulation in the switch. Inspect the switches in the gear box area and if they are located under the gear box they must be:

(1) Cleaned and sealed at the switch case parting surfaces with polyethylene, vinyl or rubber cement and reinstalled in the same location; (use minimum cement to assure that none gets inside switch) or

(2) Replaced with new switches installed in a location to preclude oil contamination. Beechcraft Service Bulletin 35-21, A35-14, B35-7, and C35-5, dated June 1, 1953, and Supplement dated August 15, 1953, provide an acceptable procedure for relocation of the switches.
