AD/BN-2/46 Engine Control Shaft - Inspection NK
Applicability: All models.
Requirement: 1. Inspect the right hand end of the engine control pivot shaft P/N NB-47-B-069 in the engine console for presence of a drilled hole, plain washers and a retaining splitpin as per Fig. 3, Section 5.1/8 of Britten Norman Parts Catalogue.
- If undrilled, drill shaft and fit washers and splitpin as per Fig. 3, Section 5.1/8 of above parts catalogue.
Compliance: Within 50 hours time in service after 4 June 1980.
Background: Due to absence of a drilled hole and retaining splitpin, an engine control pivot shaft became partially withdrawn from the engine console during taxi, causing collapse of control levers and friction discs.
