Airworthiness Directive · Amendment 39-9973 · McCauley Propeller Systems 1A103/TCM Series Propellers
McCauley Propeller Systems 1A103/TCM Series Propellers
Superseded. A later AD replaced this one: AD 2003-12-05. Comply with the one in force.
McCauley Propeller Systems 1A103/TCM series propellers with numeric serial number 770001 through 777390; and propellers with alpha-numeric serial number BC001 up to, but not including KC001; installed on but not limited to Cessna 152, Cessna A152, Reims F152, and Reims FA152 series aircraft. All alpha-numeric serial number propellers beginning with the letters "B" through "J" are affected by this AD.
This amendment adopts a new airworthiness directive (AD) that is applicable to McCauley Propeller Systems 1A103/TCM series propellers. This action supersedes priority letter AD 95-21-01 that currently requires visual inspections for cracks in the propeller hub of certain propellers using a 10X power magnifying-glass. This action requires an initial inspection for cracks in the propeller hub in accordance with a dye penetrant inspection procedure, replacement of propellers with cracks that do not meet acceptable limits, rework of propellers with cracks that meet acceptable limits, and repetitive inspections of all affected propellers. This amendment is prompted by development of a dye penetrant inspection and rework procedures. The actions specified by this AD are intended to prevent propeller separation due to hub fatigue cracking, which can result in loss of control of the aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
