Reims Aviation F406 Series Aeroplanes
| AD/F406/19 | Flap Push Rod Assemblies | 9/2009 |
Applicability: | Reims Aviation Industries (formerly Reims Aviation) Model F 406 aeroplanes with serial numbers 0093 and 0095. |
Requirement: | 1. Replace the push rod assemblies part number (P/N) 5865101-1, -7 and -9 by 2. Do not install on any aeroplane push rod assemblies P/N 5865101-1, -7 and -9. The use of later approved revisions of this document is acceptable for compliance with the requirements of this AD. Note: EASA AD 2009-0127 dated 18 June 2009 refers. |
Compliance: | For Requirement 1 - At the next scheduled maintenance check but not later than For Requirement 2 - After the effective date of this AD. |
| This Airworthiness Directive becomes effective on 27 August 2009. | |
Background: | During a scheduled maintenance check, the rod end (MS21152-1) of the flap push rod assembly has been found distorted. If left uncorrected, this condition could lead to jamming of the flap mechanism which could seriously impair the aircraft handling and potentially result in loss of control of the aeroplane. For the reasons stated above, this new AD mandates the replacement of the push rod assemblies. |
