Description

No. NE-008-22 May 14, 2008 This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, mechanics,
and certificated repair stations of recommended procedures for a “propeller search inspection” or
“general visual inspection” and performance of “cosmetic repairs”.

No. NE-08-21 May 14, 2008 This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, pilots,
mechanics, and certificated repair facilities of the potential for propeller failures on piston engine
aircraft due to prolonged operation in a restricted RPM (revolutions per minute) range as a
result of inaccurate tachometers, missing or improper tachometer markings, or missing or
improper instrument panel placards.

No. NE-08-20 May 14, 2008 This Special Airworthiness Information Bulletin (SAIB) alerts owners, operators, pilots, mechanics, and certificated repair facilities of concerns for possible failures of variable pitch propellers due to inadequate propeller maintenance

No. NE-08-19 May 14, 2008 This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, pilots,
mechanics, and certificated repair stations of concerns for potential propeller failures, aircraft
damage, and potential loss of aircraft control for certain untested propellers installed on
experimental aircraft.

No. NE-08-18 May 14, 2008 This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, pilots,
mechanics, and certificated repair facilities of the potential for propeller failure due to high
vibratory stress induced by worn or improper engine crankshaft dampers.

No. NE-07-53 September 25, 2007 This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, and certificated repair facilities of any aircraft equipped with any propeller, inspected or overhauled by Desert Aircraft Blade Service (Air Agency Certificate No. D9BR993J), of potential propeller nonconformities that might exist. A field service difficulty report concerning two Hartzell Propeller Inc. model HC-92ZK-2B two-bladed propellers (S/Ns 1349F and 1350F) installed on a Piper PA-23-23 airplane. The airplane was ground run and the mechanic noted there was an unusual vibration. The propellers were removed and sent to another propeller repair station for evaluation. An FAA Flight Standards Principal Maintenance Inspector (PMI) witnessed the subsequent teardown of these two propeller assemblies. During the teardown inspection, several nonconformities were discovered.

No. CE-06-62 August 14, 2006 This Special Airworthiness Information Bulletin (SAIB) alerts you of an airworthiness concern regarding Piper Models PA-28R-200 Arrow, serial numbers 28R-35001 through 28R-35820 or 28R-7135001 through 28R-7135229; and PA-28R-200 Arrow II serial numbers 28R-7235001 through 28R-7635545 airplanes. This SAIB explains and clarifies
information between the requirements of Airworthiness Directive (AD) 2002-09-08 and Piper Service Bulletin 1164 concerning remarking of the tachometer to avoid continuous operation between 2,000 and 2,350 revolutions per minute (rpm).

No. NE-06-13 December 12, 2005 This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, pilots, mechanics, and certificated repair facilities of all turboprop airplanes using propellers with four or more blades, to check propeller idle RPM settings and any propeller RPM restrictions or limitations, and to adhere to the propeller RPM restrictions or limitations. We recently learned of several turboprop aircraft with engine idle speeds set within the propeller restricted RPM range, which could become a potential safety of flight
issue.

No. NE-01-19 March 20, 2001
The FAA revoked Southern California Propeller Service's (SCPS) certificate (# VXSR617L) as a propeller repair station, on June 16, 1998, for performing improper maintenance and overhauls. These improper overhauls show corrosion signs, which could serve as the point of origin for cracks, and fatigue cracks that could propagate to blade failure, resulting in the loss of aircraft control.

No. ACE-99-35
September 15, 1999
A recent propeller repair station audit has revealed that certain blade face alignment, chordwise and thickness inspections were not properly accomplished in accordance with the manufacturer’s propeller overhaul manual procedures. This discovery has prompted an investigation to gather data so that it can be determined whether an airworthiness directive is required. There have been no reports of propeller failures; however, a propeller blade failure can result in the loss of aircraft control. This is considered a significant safety issue and all owners/operators are requested to report any problems with propellers that were overhauled by Santa Monica Propeller Service, Inc. between the dates January 1997 to March 1999. Santa Monica Propeller Service, Inc. is located at 3135 Donald Douglas Loop South, Santa Monica, California 90405; Telephone (310) 390-6233, (800) 421-9995, Facsimile (310) 398-3471. This Special Airworthiness Information Bulletin (SAIB) is applicable to owners/operators of all Hartzell and McCauley Propeller models that have had their respective propellers overhauled by Santa Monica Propeller Service, Inc during this time period. Please review the attached compiled listing of identified propeller models and serial numbers to determine if this SAIB is applicable. This is not an exhaustive list as there may be other propellers that were overhauled by Santa Monica Propeller Service, Inc. not listed in this SAIB.

No. ANE-99-23 June 10, 1999 The purpose of this Special Airworthiness Information Bulletin (SAIB) is to alert owners/operators of Piper PA-44-180 and Raytheon (Beech) 76 aircraft of possible hub arm failure. This SAIB is issued for informational purposes only and any recommendation for corrective action is not mandatory.
