Airworthiness Directive · Amendment 39-15453 · McCauley Propeller Systems Propeller Models B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0
McCauley Propeller Systems Propeller Models B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0
Superseded. A later AD replaced this one: AD 2009-19-04. Comply with the one in force.
This AD applies to McCauley Propeller Systems propeller models B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0. These propellers are installed on BAE Systems (Operations) Limited Jetstream Model 4100 and 4101 series airplanes (Jetstream 41).
The FAA is superseding three existing airworthiness directives (ADs) for McCauley Propeller Systems propeller models B5JFR36C1101/ 114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0. Those ADs currently require fluorescent penetrant inspections (FPI) and eddy current inspections (ECI) of propeller blades for cracks, and if any crack indications are found, removing the blade from service. This AD requires the same initial inspections, but extends the compliance times and intervals, adds repetitive inspections, and mandates a life limit for the blades. This AD results from our determination that we must require repetitive inspections for cracks, and from reports of blunt leading edges of the propeller blades due to erosion. We are issuing this AD to detect cracks in the propeller blade that could cause failure and separation of the propeller blade and loss of control of the airplane, and to detect blunt leading edges on the propeller blades, which could cause airplane single engine climb performance degradation and could result in an increased risk of collision with terrain.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Remove all 114GCA-0, L114GCA-0, 114HCA-0, and L114HCA-0 propeller blades upon reaching 10,000 operating hours time-since-new.
Perform an initial fluorescent penetrant inspection and eddy current inspection of propeller blades. Use the Equipment Required and Accomplishment Instructions of McCauley Propellers Alert Service Bulletin ASB255, dated January 8, 2007, and the following compliance schedule:
| If the propeller blade: | Then inspect the propeller blade: |
|---|---|
| (1) Has more than 2,400 operating hours time-since-new (TSN), time-since-last inspection (TSLI), or time-since-overhaul (TSO) | Within 100 operating hours time-in-service (TIS) after the effective date of this AD. |
| (2) Has 2,400 or fewer operating hours TSN, TSLI, or TSO | Upon reaching 2,500 operating hours TSN, TSLI, or TSO. |
Remove from service propeller blades found with any crack indications. Blades found with crack indications are no longer eligible for installation in any configuration. Do not install them in any configuration on any airframe.
(i) Thereafter, inspect the propeller blades within 2,500 operating hours TSLI or TSO. Use the Equipment Required and Accomplishment Instructions of McCauley Propellers Alert Service Bulletin ASB255, dated January 8, 2007.
Every time the propeller is removed for the inspection for cracks, inspect the blade for erosion and, if necessary, repair the erosion. The McCauley Propeller Systems Blade Overhaul Manual No., BOM 100, contains information on inspecting and repairing erosion on the propeller blade.
Within 10 calendar days of the inspection, use the Reporting Form for Service Bulletin 255 to report all inspection findings to McCauley Propeller Systems, P.O. Box 7704, Wichita, KS 67277-7704, telephone (800) 621-7767.
(l) The Office of Management and Budget (OMB) has approved the reporting requirements and assigned OMB control number 2120-0056.
