1、Lessons Learned Entry: 1625Lesson Info:a71 Lesson Number: 1625a71 Lesson Date: 2005-06-23a71 Submitting Organization: DFRCa71 Authored by: Michael TobermanSubject: Flyable Storage Aircraft Maintenance Procedures Abstract: Problems were experience bringing NASA F-15 837 back to flight status after no

2、t flying for over 18 months. The problems resulted in cost and schedule slips that could have been prevented if a plan was established to operate some of the components at specified time intervals. The time and expense to perform this type of maintenance is necessary in order to effectively preserve

3、 Drydens aging fleet of aircraft. Description of Driving Event: The problem was related to the aircraft sitting for such a long time without being operated. There were multiple problems bringing 837 back up to flight status, none of which were related to the unique configuration of the aircraft. The

4、y included multiple hydraulic leaks and a Generator Failure. Since we did not have engines there was a limited amount of operations that could have been done on the aircraft to lubricate seals and operated components, but a plan that identified what could have been tested in the state that the vehic

5、le was in, could have reduced the time required to bring the aircraft back up. Lesson(s) Learned: Ensure that an aircraft that is in flyable storage or in an extended down time has a plan in place to operate as many of the systems as possible within a given time period. Recommendation(s): Establish
