Airworthiness Directives; Piaggio Aero Industries S.p.A.


AGENCY:
 
Federal Aviation Administration (FAA), Department of Transportation (DOT).


ACTION:
 
Final rule; rescission.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are rescinding an airworthiness directive (AD) for all Piaggio Aero Industries


S.p.A Model P-180 airplanes. That AD was prompted by mandatory continuing airworthiness


information (MCAI) issued by the airworthiness authority for Italy. We issued that AD to prevent the


brake hydraulic fluid from leaking because of the brake assembly rods contacting the brake valve


tubing, which could result in the inability to adequately stop the airplane during ground operations.


Since we issued that AD, we have determined this is no longer an unsafe condition and that regularly


scheduled annual inspections address this subject.


DATES:
 
This AD is effective November 21, 2012.

SUPPLEMENTARY INFORMATION:


Discussion


We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by rescinding AD


2000-07-11 (65 FR 19305, April 11, 2000) that applies to the specified products. That NPRM was


published in the Federal Register on July 19, 2012 (77 FR 42454). The MCAI states:


After a 1999 training session during which conflicting inputs were given to the brake


pads between pilot and copilot, a brake system rod was found deflected. The rod, in


this bent condition, could possibly wear and damage the tubings connected to the


brake valves, with consequent fluid leakage.


Prompted by these findings, PAI issued Service Bulletin (SB) 80-0107, providing


instructions for repetitive inspections of the affected rods and tubings. As this was


considered to be a potentially unsafe condition, Registro Aeronautico Italiano (RAI),


the predecessor of ENAC (Ente Nazionale per l'Aviazione Civile), issued Prescrizione


di Aeronavigabilit[agrave] (PA) No. 1999-219, which required the repetitive


inspections as detailed in PAI SB 80-0107 and, depending on findings, replacement of


rod or tubing.


Since that AD was issued, the repetitive inspections of SB 80-0107 have been


included as regular tasks into the maintenance schedule of both Avanti and Avanti II


aeroplanes. In addition, no other cases of brake system bent rods have been reported,


nor have any rods been replaced for damage in the P.180 fleet since that occurrence.


Based on the available information, this is no longer considered to be an unsafe


condition. Prompted by this determination, PAI issued Revision ZZ of SB 80-0107,


which cancels the original SB 80-0107.


For the reasons described above, this Notice is issued to cancel ENAC PA no. 1999-


219 dated 03 May 1999.


Comments


We gave the public the opportunity to participate in developing this AD. We received no


comments on the NPRM (77 FR 42454, July 19, 2012) or on the determination of the cost to the


public.


Conclusion


We reviewed the relevant data and determined that rescinding the AD will not affect air safety


and will reduce the burden on the public. We will rescind the AD as proposed except for minor


editorial changes. We have determined that these minor changes:


•
 
Are consistent with the intent that was proposed in the NPRM (77 FR 42454, July 19, 2012)


for correcting the unsafe condition; and


•
 
Do not add any additional burden upon the public than was already proposed in the NPRM


(77 FR 42454, July 19, 2012).
