Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Issue and airworthiness directive (AD) to require the installation of the one-piece, integral sleeve spacer at all six locations in the high-pressure compressor rotor of Pratt & Whitney JT8D-series engines not so equipped. The installation should be made as soon as practical but not later than the next opportunity wherein the engine is available in a maintenance facility where a partial or complete disassembly of the compressor can be accomplished. (Superseded by A-86-28)
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to issue an airworthiness directive requiring the installation of a one-piece integral sleeve spacer at all six locations in the high-pressure compressor rotor of Pratt & Whitney JT8D-series engines that are not already equipped with it. The installation must be done as soon as practical, but no later than the next opportunity when the engine is at a maintenance facility where partial or complete disassembly of the compressor can be performed.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
