For aircraft with 200 or more hours' time in service, compliance is required within 10 hours' time in service after the effective date of this AD. For aircraft with less than 200 hours' time in service, compliance is required within 25 hours' time in service after the effective date of this AD, or before 210 hours' total time in service is exceeded whichever occurs first.
To preclude loss of aileron control, accomplish the following:
(a) Replace the aileron cable control sector support brackets, upper and lower, in lower wing panels with new support brackets, P/N 1854-13 (Kit of replacement parts, A1854, furnished by Grumman), or FAA approved equivalent. Install the parts and the aileron cables in accordance with Grumman Aircraft Engineering Corp. Mandatory Service Bulletin No. 20 dated January 24, 1962, or FAA approved equivalent.(b) Visually inspect aileron control system pushrod assemblies, Grumman P/N's A1866-1 and A1866-3, in both lower wing panels, for loose rod end fittings due to elongation of rivet holes. Repair or replace loose fittings prior to further flight. After initial compliance, visually inspect the aileron control system pushrod assemblies at each periodic inspection thereafter until one of the following, or FAA approved equivalent is accomplished:
(1) Insert aluminum alloy bar, 2024-T3, 7/16 O.D. x 7/8-inch plugs in each end of A1866-11 and A1866-13 tubes and reinstall the rod ends with two AN 470-AD5 rivets per rod end.
