Airworthiness Directive · Amendment 39-18664 · Stabilizers
REIMS AVIATION S.A. Airplanes
This AD applies to REIMS AVIATION S.A. F406 airplanes, serial numbers F406-0001 through F406-0098, certificated in any category.
We are adopting a new airworthiness directive (AD) for certain REIMS AVIATION S.A. Model F406 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks found in the horizontal stabilizer rear attach structure and the vertical fin rear spar attach structure. We are issuing this AD to prevent structural failure of the horizontal stabilizer and/or the vertical fin rear spar attach structure, which could result in damage to the airplane and loss of control.
Unless already done, do the following actions:
(1) At whichever of the compliance times specified in paragraphs (f)(1)(i) through (iii) of this AD that occurs the latest after November 2, 2016 (the effective date of this AD), and repetitively thereafter every 2,400 hours time-in-service (TIS), do a visual and non-destructive test (NDT) inspection of the horizontal stabilizer splice plate assembly, part number (P/N) 6032183-1 or P/N 406-5518-32183-100 (as applicable), and the attach structure assembly P/N 6031210-1. Do the inspections following the Accomplishment Instructions in ASI Aviation Service Bulletin CAB01-5 Rev 2, dated December 3, 2015.
(i) Before accumulating 2,500 hours TIS; or
(ii) Within the next 100 hours TIS; or
(iii) At the next 600-hour inspection.
(2) During any inspection required by paragraph (f)(1) of this AD, if any oversized bolt hole or crack is detected on the horizontal stabilizer splice plate assembly or attach structure assembly, before further flight, repair or replace the affected part with a serviceable part following the Accomplishment Instructions in ASI Aviation Service Bulletin CAB01-5 Rev 2, dated December 3, 2015. After taking the necessary corrective action, continue with the repetitive inspection specified in paragraph (f)(1) of this AD.
