Applicability: Model 717-200 aircraft, fuselage numbers 5002 through 5106.

Requirement: Inspect in accordance with the technical requirements of FAA AD 2003-04-24 Amdt 39-13073 refers.

Background: The FAA received reports of cracking on a support fitting for the main spoiler actuator on several Model 717-200 aircraft.

This damage resulted in cracking of the rear spar and fuel seepage.
