The airworthiness directive
59-07-05 PIPER: Applies to PA-24-180 Comanche Aircraft.
Compliance required not later than June 1, 1959.
Inspection has shown the clearance between oil cooler lines and exhaust stack is not adequate on some aircraft. Clearance between the lines and the stack should be a minimum of three-eights of an inch. In the event inadequate clearance exists, the oil cooler lines should be reformed or the fittings in the cooler should be repositioned slightly so that proper clearance can be obtained. If necessary, adapters Piper P/N 451 855 (Weatherhead No. 3200 x 6) can be installed between the oil cooler and the oil cooler line fittings.
When providing for the proper clearance make certain there is no interference between the oil cooler lines and the cowl.
(Piper Service Bulletin No. 167 dated January 6, 1959, covers this item.)
