The 2010 rule amended FAA regulations pertaining to certification and operation of transport category airplanes to preclude widespread fatigue damage in those airplanes. For existing airplanes with a maximum gross takeoff weight greater than 75,000 pounds, the rule required design approval holders to establish limits of validity (LOV) of the engineering data that supports the maintenance program. For new airplanes, the rule required all applicants for type certificates of transport category airplanes to establish an LOV and demonstrate that the airplane will be free from WFD up to the LOV. The rule required that operators of affected airplanes incorporate the LOV into the maintenance program for that airplane. Operators may not fly an airplane beyond its LOV, although this rule provided means for extending that limit.
The FAA adjusted the hourly burden and costs to reflect that all affected design approval holders have complied with the requirement to establish compliance plans and sent them to the FAA for approval by April 14, 2011. Section 26.21 does not require a compliance plan to be submitted to the FAA for approval after that date.
