A tous les propriétaires d'avion "VAN’S AIRCRAFT" RV-3, 4, 6/6A, 7/7A, 8/8A, 9/9A, 10, and 14/14A

L'EXPERIMENTAL AIRCRAFT ASSOCIATION (EAA) vient de publier sur leur site Internet un Service Bulletin d'importance pour les avions de la compagnie VAN'S AIRCRAFT.

Ce Service Bulletin demande une inspection visuelle avant le prochain envolé.

Ça concerne une fissure potentielle sur le longeron arrière (wing aft spar web) au niveau du point d'attachement des rivets de la penture intérieur des ailerons (inboard aileron hinge bracket attach rivets). Voir ci inclus :


Trouvé un aperçu en Anglais émit par “VAN’S AIRCRAFT (en Anglais seulement).

Synopsis: Cracks have been found radiating outward from the lower or upper most rivets that attach the inboard aileron hinge brackets to the webs of the wing rear spars. See Figure 1. On RV-10 or RV-14/14A aircraft, there is a potential for cracks in the flange bends of the inboard aileron hinge brackets (though there is no record of any at the time this S.B. was issued)

Time of Compliance: Inspect before further flight.

- If no cracks are detected, re-inspect at every annual condition inspection or until the modifications required by this service bulletin have been completed.

- If cracks are detected, the modifications required by this service bulletin must be completed before further flight.


VAN’S AIRCRAFT: SERBICE BULLETIN 16-03-28 (RÉSUMÉ)

SERVICE BULLETIN 16-03-28 Date Released: May 6, 2016 (Initial Release) June 2, 2016 (Added Note, pg.11) Date Effective: May 6, 2016

Affected Models: All RV-3, 4, 6/6A, 7/7A, 8/8A, 9/9A, 10, and 14/14A aircraft.

Subject: Cracking of wing aft spar web at the inboard aileron hinge bracket attach rivets. In addition, for RV-10 and RV-14/14A aircraft, there is a potential for cracking of the flange bends of the inboard aileron hinge brackets. Required Action: For RV-3/3A/3B, 4, 7/7A, 8/8A, 9/9A aircraft: Inspect for cracks as described in this document. If cracks are present in the spar web, stop drill the cracks and install aileron attach doublers as described in this service bulletin. For RV-10 and RV-14/14A aircraft: Inspect for cracks as described in this document. If cracks are found in the spar web or the inboard aileron brackets, stop drill the cracks in the spar web (if present), install aileron attach doublers, and replace the aileron hinge brackets with updated brackets. It is unlikely that RV-6/6A wings will be affected. If cracks are present in RV-6/6A aircraft, email Van’s Engineering Dept for instructions, with photos of the cracks, for a specific repair scheme. Contact Van’s Aircraft to obtain the parts needed to complete this modification for your specific model. See the SB kit part numbers at the end of this document

Inspection complétée le mois dernier et tout est OK. Les avions avec problèmes sont excessivement rare. Je crois que l'on peut les compter sur les doigts de la main.

Messieurs,

C'est ordinairement tous que ça prend (en avoir 3 ou 4 rapporté aux autorités (FAA ou TC)) pour émettre une « Directive Aéronautique (Airworthiness Directive (AD)).
