Background: | The FAA requires repetitive inspections of the inboard tracks of the outboard trailing edge flaps to detect discrepancies which, if not corrected, could result in loss of the outboard trailing edge flaps and consequent reduced controllability of the aircraft. This amendment allows the use of an FAA approved alternative means of compliance (AMOC) for some inspections that are specified in the requirement section of this Airworthiness Directive. |
| The original issue of this Airworthiness Directive became effective on 13 June 2002. |
