McCauley Propeller Systems Five-Blade Propeller Assemblies
Superseded. A later AD replaced this one: AD 2010-23-06. Comply with the one in force.
This AD applies to McCauley Propeller Systems propeller assemblies, part numbers (P/Ns) B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0. These propeller assemblies are installed on BAE Systems (Operations) Limited Jetstream Model 4100 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for certain McCauley Propeller Systems propeller assemblies installed on BAE Systems (Operations) Limited Jetstream model 4100 series airplanes. This AD requires removing certain propeller hubs from service at new reduced life limits and eddy current inspections (ECIs) of the propeller hub. This AD results from three reports of cracked propeller hubs. We are issuing this AD to prevent cracked propeller hubs, which could cause failure of the propeller hub, blade separation, and loss of control of the airplane.
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 any propeller hub from service that is currently, or ever was, operated on an engine with a water-methanol assist system, not later than 6,000 hours time-in-service (TIS).
(g) Remove any other propeller hub from service not later than 18,000 hours TIS.
(h) Remove any propeller hub from service that exceeds its life limit on the effective date of this AD, within 50 hours TIS after the effective date of this AD.
(i) Any propeller hub removed from service after exceeding its life limit must not be returned to service on any installation.
For all installed propeller hubs, perform an eddy current inspection (ECI) within 200 hours TIS or 60 days after the effective date of this AD, whichever occurs first. Use the Accomplishment Instructions of McCauley Alert Service Bulletin (ASB) No. ASB250, dated September 12, 2005, to do the inspection.
Thereafter, for all installed propeller hubs with 12,000 or more hours TIS:
(1) Perform repetitive ECIs within 1,800 hours TIS or 12 months, whichever occurs first.
(2) Use the Accomplishment Instructions of McCauley ASB No. ASB250, dated September 12, 2005, to do the inspections.
(l) This AD does not require repetitive inspections for propeller hubs that ever operated on, or are currently operating on, engines with a water-methanol assist system, due to the 6,000 hours TIS hub reduced life limit.
Report within 10 calendar days of the inspection, the results that equal or exceed the reject criteria to:
(1) The FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Wichita, KS 67209, Attention: Jeff Janusz, telephone (316) 946-4148; e-mail: jeff.janusz@faa.gov; and
(2) McCauley Propeller Systems, P.O. Box 7704, Wichita, KS 97277-7704.
(3) Reporting requirements have been approved by the Office of Management and Budget (OMB) and assigned OMB control number 2120-0056.
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.
