Now Continental wants you to borescope the cylinders at annual. I can here the prosecuting attorney asking "Mr. Pierce why didn't you borescope the cylinders?" Oh boy. Can you say liability?
AFFECTED: All Teledyne Continental Motors (TCM) engine models.
F.A.A. Advisory Circular (AC) 43.13-1. Chapter 8, Section 1, paragraph 8-1 states; ? Consult the
manufacturer?s manuals, service bulletins and instruction books regarding the repair and overhaul, inspection,
installation, and maintenance of aircraft engines, for that particular make, model and type of engine. This
section lists acceptable inspection and repair procedures that may be used in the absence of an engine
manufacturer?s maintenance information.? The following procedures are to be used as the standard for
performing a cylinder differential pressure test on all TCM engines. Reference 14 CFR Part 43.13.
A. CYLINDER CONDITION DISCUSSION
The cylinder differential pressure test has become a widely used method of assisting in determining the
internal condition of cylinders and cylinder components. As with any test or inspection the cylinder
differential pressure test has certain limitations that necessitate its use in conjunction with other non-invasive
inspections. TCM requires a cylinder borescope inspection be accomplished in conjunction with the
differential pressure test.
