AMC 25.745(c) Nose-wheel steering

ED Decision 2003/2/RM

1       No failure or disconnection need be assumed in respect of parts of proven integrity e.g. a simple jack or manual selector valve, but slow leakage from pipe joints and fracture of pipes should be considered as probable failures.

2       In assessing where the inadvertent application of steering torque as a result of a single failure would lead to danger, allowance may be made for the pilot’s instinctive reaction to the effects of the fault. However, dependent on the urgency and rapidity of warning of the failure given to the pilot, allowance should be made for a reaction time before it is assumed that the pilot takes any corrective action.
