Plain English Summary

3/10 complexity

This AD requires operators of Pratt & Whitney JT8D-200 engines (except those that have incorporated P&W SBs 5514 and 5945) to implement a recurring inspection program to monitor oil temperature in the number 4 and 5 bearing compartments, carried out per Pratt & Whitney Service Bulletin No. 5944 Revision 2.

Issued after 28 high‑pressure turbine shaft fractures (five uncontained), it set compliance from 17 Sep 1992 and places implementation costs and responsibilities on operators or their MROs.
