| Background: | This Directive has been issued to re-introduce additional FAA requirements for the main landing gear wheel well pressure floor. FAA AD 91-22-08 was prompted by several reports of cracking in areas adjacent to a previously installed modification and not required to be inspected. This Directive requires additional inspections of aircraft on which the modification has been installed, requires inspections of additional aircraft on which the modification was incorporated in production, requires an expanded inspection area for unmodified aircraft, reduces the initial inspection threshold, and limits the time that blind rivets may be used. |
