AD A300 / A310

Message par Poncho (Admin) le Ven 9 Sep 2011 - 13:27

Bonjour à tous
Dans la lignée de l'A300 d'AA tombé du ciel de new york sans sa queue
L'EASA propose la mise en place d'un avertisseur pour manoeuvre excessive de la gouverne de direction

Et s'interroge sur les implications pour la certif des avions

http://www.flightglobal.com/articles/2011/09/09/361767/easa-to-order-a300-operators-to-fit-rudder-reversal.html


Airbus A300 and A310 operators will be instructed to fit a warning device designed to prevent crews from making potentially hazardous rudder inputs of the kind that brought down an American Airlines jet 10 years ago.
The accident occurred on 12 November 2001, when the A300's vertical fin broke away as flight AA587 climbed out of New York Kennedy airport.
Investigators found that the pilot commanded a series of five heavy rudder inputs, alternately deflecting the rudder in one direction then the other, intending to counter a roll disturbance induced by wake turbulence. These rudder reversals exerted excessive loads on the fin and it sheared off.
While the sequential rudder inputs were "unexpected" and "non-conventional", the European Aviation Safety Agency said, the results of a pilot survey published at the end of 2010 indicated that the rudder "is still reported to be used or considered for use by pilots in ways they have not been trained".
It added that the actions "sometimes contradict" industry guidance on aircraft upset recovery.
EASA has approved a design change involving installation of a "stop rudder inputs" warning system, and is proposing to order A300-600 and A310 operators to fit the device within four years.
The equipment monitors rudder inputs and triggers both aural and visual warnings if it detects a single "dangerous" rudder doublet.
EASA said it is still co-operating with the US Federal Aviation Administration to determine whether, and to what extent, certification standards for large transport aircraft can be amended to take into account possible excessive use of the rudder.


Bonne journée

Des criques dans les "capots" de pompes à kéro dans les réservoirs des A310-300 ..
A changer bientôt, demande d'AD en cours !
C'est potentiellement dangereux !
Réclamé par les Américains ! (M'est avis que ce sont des pompes US, en plus)

Les fixations des gouvernes de queue,le Trim dans cas sur les A300 en cause ... potentiellement dangereux ... les queues des A300-330, c'est assez (Trop) souvent ... que l'on en parle ...

----------- Le lien et un extrait -------------

https://www.federalregister.gov/articles/2012/05/03/2012-10471/airworthiness-directives-airbus-airplanes

We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes. This AD was prompted by analysis that in a specific failure case of the upper primary attachment of the trimmable horizontal stabilizer actuator (THSA), the THSA upper secondary attachment engaged because it could only withstand the loads for a limited period of time. This AD requires installing three secondary retention plates for the gimbal bearings on the THSA upper primary attachment. We are issuing this AD to prevent failure of the secondary load path, which could result in loss of control of the airplane.

Bonjour !

Suite à l'accident de l'300 de AA il y a 10 Ans !
La FAA et Airbus tournent toujours autour des mesures à prendre !
La vraie solution, de renforcer cette gouverne n'a pas été retenue !
Assez navrant !
La seule consigne est : Pilotez moins violemment votre Avion, si vous ne voulez pas que ça casse !

Bien, ça ressort (Et avec raison) sur USA Today !
