Possible Inspection à venir sur les PIPER PA-28 & PA-32?
Posted: Thu 27 Dec, 2018 23:26
La FAA est en train d’étudier à savoir s’ils vont produire une Directive de Navigabilité (AD) contre les PIPER CHEEROKE, ARROW & CHEEROKE SIX (PA-28-XXX et PA-32-XXX) suite à l’accident survenu en Floride le 4 avril 2018, sur un PIPER ARROW (PA-28R-201) de l’« Embry Riddle Aeronautical University (ERAU) » à l’aéroport de Daytona Beach International. Au moment de l’accident l’avion avait moins de 8,000 heures de vol et n’avait que 25 heures depuis l’inspection annuelle. Lorsque une aile se détachas de l’avion près de l’enplenture, au décollage à environs 900 pieds AGL après un posé décollé. Il fût déterminé que l’aile se sépara due à de multitude fractures due à la fatigue dans l’aluminium du longeron principale qui avait débuté aux alentours des trous des boulons d’attache d’aile.
Cette procédure pourrait s’appliquer à environ 20,000 avions aux États-Unis seulement et combien (?) au CANADA? L’inspection des longerons principales s’appliquerons au avion ayant 5,000 heure et plus de vol depuis l’origine ou depuis le remplacement des ou du longeron(s) principale.
Selon l’article, l’inspection devrait prendre 1,5 heures de mécanicien (à $90.00/ l’heure x 1,5 heures = $135.00). Cependant s’il faut changer un (1) « SPAR » alors ça va coûter cher un estimé en dollar américain ($USD) de $8,260USD ($11,375.08 CDN).

Proposed AD Could Affect 20,000 Pipers, December 24, 2018
KATE O'CONNOR (AVWEB Magazine)
The FAA has issued a notice of proposed rulemaking (NPRM) regarding the adoption of an airworthiness directive (AD) that would require wing spar inspections on nearly 20,000 Piper aircraft. According to the FAA, the AD comes after an investigation into the report of a fatigue crack on a Piper PA-28R-201 “revealed that repeated high-load operating conditions accelerated the fatigue crack growth in the lower main wing spar cap.” The FAA also noted that the area where the crack was found was “inaccessible for a visual inspection.”
The proposed AD would cover PA-28 and PA-32 aircraft with wing spar structures similar to the PA-28R-201. It would apply to aircraft that have 5,000 or more hours time-in-service (TIS), have had a main wing spar replaced with a spar with more than zero hours TIS or have missing or incomplete maintenance records. The AD would require “calculating the factored service hours for each main wing spar to determine when an inspection is required, inspecting the lower main wing spar bolt holes for cracks, and replacing any cracked main wing spar.”
The FAA estimates that 19,696 U.S.-registered aircraft would be affected. According to the administration, the inspection would take approximately 1.5 hours and cost $147.50 USD ($202.50 CDN) per wing spar. Estimated cost of replacing a wing spar is $8,260USD ($11,375.08 CDN) per spar.
The proposed AD is an interim action. The FAA has stated that it could initiate further rulemaking based on the data gathered by inspection reports. The AD is open for comments until Feb. 4, 2019. Comments can be made and the complete text of the proposed AD (FAA-2018-1046) can be viewed at regulations.gov.
NTSB Report Out on Fatal Embry Riddle Crash
The board issued its preliminary findings on the crash. Here’s what to expect next.
Published April 20, 2018, (Plane&Pilot Magazine)
The NTSB has issued its preliminary, factual report on the crash of a 2007 Piper Arrow PA-28-R201 on April 4th, 2018. Zachary Capra, 25, an Embry Riddle Aeronautical University (ERAU) student was taking a checkride with 61-year-old FAA designated flight examiner John Azma. On takeoff following a touch and go landing on Runway 25L at Daytona Beach International Airport the plane was climbing out and at approximately 900 feet agl it went out of control and crashed, killing both occupants instantly. Investigators immediately discovered that the plane’s wing had detached in flight, causing the Arrow to go out of control.
In its report the NTSB found that the wing that broke off suffered from metal fatigue in multiple locations. At the time of the accident, the plane had just less than 8,000 hours total time and had accumulated just over 25 hours since its last annual inspection. In its report the NTSB found that “left wing separated from the fuselage near the wing root and exhibited mid-span buckling of the surface skin…..and that ..”preliminary examination of the left wing main spar revealed that more than 80 percent of the lower spar caps and portion s of the forward and aft spar doublers exhibited fracture features consistent with metal fatigue.”
In the wake of the accident, ERAU grounded its fleet of Arrows indefinitely. The FAA has yet to issue guidance for increased inspections of the affected aircraft models, though it is likely that the FAA will issue an AD for inspections of the wing of some range of PA-28 aircraft at some point soon.
