La ''FAA'' considère une "Directive de Navigabilité (Airworthiness Directive (AD))" sur certain "Vilebrequin (Crankshaft)" de "SUPERIOR AIR PARTS (SAP)" installé sur des moteur "SUPERIOR" et/ou "XP" de modèles : IO-360, O-360 et/ou "LYCOMING" de modèles : AEIO-360, IO-360 et O-360.

Un estimé de 115 "Vilebrequins (Crankshafts)" de "SUPERIOR AIR PARTS (SAP)" pourrait être affecté! Qui demanderont peut être d’être enlevé ou remplacé dans les moteurs? L’"American Owners & Pilots Association (AOPA)", es sur le dossier. Le coût estimé par la FAA pour remplacé le "Vilebrequin (Crankshaft)" de SAP, es de 14,821 $ USD (20,300 $ CDN), par moteur.

Les moteurs pouvant être affecté ont reçu un "ilebrequin (Crankshaft)" produit entre 2012 et 2014. Le "Vilebrequin (Crankshaft)" de "SUPERIOR AIR PARTS (SAP)" peut causer un accident. Par, une soudaine perte de puissance complète et peut aller jusqu’à un "Atterrissage d’urgence"! À date, ils y à eu trois (3) accidents / incidents qui ont eu lieu le 6 mars 2017, le 3 août 2017 et le 31 octobre 2018. La "FAA" à déterminé à date que les trois (3) accidents / incidents sont des résultats de brisures par "Fatigue du matériel (Material Fatigue)"! Si, la "Directive de Navigabilité (Airworthiness Directive (AD))" sur certain "Vilebrequin (Crankshaft)" de "SUPERIOR AIR PARTS (SAP)" est émise? Tous les aéronefs affecté seront "Cloué au sol" immédiatement et n’aurons le droit de ne faire qu’un (1) envolé, jusqu’au point ou le "Moteur" sera ouvert pour le remplacement du "Vilebrequin (Crankshaft)’’ de "SUPERIOR AIR PARTS (SAP)"!

After investigating three Superior Air Parts crankshaft assembly failures that caused loss of power and "immediate or emergency landings” on March 6, 2017; August 3, 2017; and October 31, 2018, the FAA “determined that the crankshaft assembly failures resulted from the manufacturing process at [Superior Air Parts’] crankshaft vendor during 2012 and 2014.” Analysis determined that all three failures were the result of fatigue cracking, the FAA notice said.


FAA CONSIDERS SUPERIOR AIR PARTS CRANKSHAFT ASSEMBLY AD

February 12, 2020 By Dan Namowitz

The FAA has proposed an airworthiness directive (AD) requiring the removal from service of some Superior Air Parts crankshaft assemblies used on all SAP Model IO-360-series and O-360-series reciprocating engines and certain Lycoming engines following three loss-of-power accidents tied to fatigue cracking of the crankshaft assemblies.

The AD, which affects an estimated 115 crankshaft assemblies installed on U.S.-registered normal-category aircraft, includes Lycoming engine models AEIO-360-, IO-360-, and O-360-series engines if they have a Superior Air Parts crankshaft assembly with designated part numbers installed. The crankshaft assemblies were installed as original equipment on the affected Superior Air Parts engines and under parts manufacturer approval on the Lycoming engines, according to a notice published January 29.

The FAA will accept comments from the public on the proposed AD until March 16.
“AOPA plans to respond after carefully reviewing all supporting data and alternatives to ensure the least amount of burden to those impacted by this proposed AD,” said Christopher Cooper, AOPA director of regulatory affairs.
AOPA will insist that the method of compliance required be based on the most cost-effective and least intrusive means possible, while maintaining an equivalent level of safety, he said.
According to the FAA, the estimated cost of a full crankshaft replacement is $14,821.

The proposed AD would permit a one-time special flight permit to fly the aircraft to a maintenance facility to comply with the AD. Limitations would include no passengers, VFR day conditions only, and avoiding areas of known turbulence.

Comments on the proposed AD may be submitted by March 16 online or by mail to U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. Please include Docket No. FAA-2018-1077 and Product Identifier 2018-NE-40-AD at the beginning of your comments.
