SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   60-12-01 CONTINENTAL: Amdt. 153, Part 507, Federal Register May 17, 1960. Applies to E185-8, E185-9, E185-11, E225-4 and E225-8 Engine Models.

Compliance required at next periodic inspection, but not later than September 1, 1960.

An inflight failure has indicated that additional information regarding engines affected by replacement requirements of AD 56-06-01 should be provided. This AD is therefore issued to supply specific serial numbers of engines that were rebuilt (remanufactured) between April 1, 1954 and May 1, 1955. The affected engines are:

Remanufactured E185-8, -9 and -11 Engines: 25015, 25037, 25044, 25048, 25057, 25065, 25071, 25075, 25086, 15087, 25137, 25141, 25162, 25189, 25202, 25210, 25220, 25234, 25243, 24254, 25269, 25288, 25307, 25320, 25325, 25333, 25376, 25379, 25381, 25387, 25422, 25426, 25464, 25518, 25526, 25545, 25562, 25575, 25578, 25611, 25649, 25718, 25754, 15761, 25766, 25767, 25783, 25790, 25795, 25819, 25834, 25897, 25930, 25950, 25957, 25958, 26003, 26088, 26095, 26104, 26121, 26138, 26304, 26321, 26327, 26343, 26352, to 26412 inclusive.

Remanufactured E225-4 and -8 Engines: 30122, 30391, 30454, 32154, 35001, 35082, 35086, 35095, 35113, 35128, 35132, 35133, 35135, 35137, 35138, 35139, 35144, 35145, 35151, to 35254 inclusive.

The above engines may have piston pin assembly P/N 530845, which is satisfactory, or piston pin assembly P/N 535145, which is unsatisfactory.

Unless previously accomplished per Continental Service Bulletin No. M56-2 dated February 14, 1956, including Supplement No. 1 dated March 12, 1956, or AD 56-06-01, replace piston pin assembly P/N 535145 with P/N 539467.

Use the applicable method of inspection outlined below to determine which piston pin assembly is installed in the above remanufactured engines:

(a) If none of the cylinders on the engine in question have been removed in the field since the engine was shipped from the factory, remove and inspect the piston pin assembly in any one of the cylinders. Continental Motors Corporation procedures provide that all cylinders will have the same piston pin assembly.

(b) If the engine in question has had any of the cylinders removed in the field since the engine was shipped from the factory, inspect those cylinders and also at least one of the factory installed cylinders which has not been disturbed.

This supplements AD 56-06-01 and supersedes AD 59-10-04.
