Bene allora al di là degli altri contributing factor che riguardano un discorso di maintenance, se analizziamo quanto segue :

During the flight with the first student, two ELAC1 + ELAC2 PITCH FAULTs were triggered (the first and third touch-down, see Appendix I) at the moment when the instructor was manually stopping the trim wheel at around 1° Nose Up when the THS was returning to 0° after touch down (ground setting). Flight control (FLT CTL) pitch normal LAW switched to alternate 1 law. Due to the fact that ELAC PITCH FAUT message is inhibited by the system in flight phases 4, 5, 7 and 8 (see Figure 21), these failure messages were not displayed on the ECAM display until the aircraft reached 1500 ft. As for this flight with the first student, each time when the aircraft reached 1500ft the ECAM alert F/CTL ELAC 1(2) PITCH FAULT were displayed on the Engine Warning Display (see Figure 1), and a single chime (SC) was triggered related to the reversion of the F/CTL LAW in Alternate. Both ELAC-s were then reset by the crew according to the manufacturers’ operational documentation during the following level flight of the flight pattern. FLT CTL pitch normal law was recovered each time after the reset. The rest of the training session with the first student was uneventful. The training session with the students was completed with a complete full stop landing, after which a new student was seated on the right seat in the cockpit and the whole session was repeated.

Una eventuale commissione d'inchiesta ti chiederebbe come mai, a seguito dell'avaria del canale pitch dei due principali F/CTL computer che governano lo stesso ed il downgrade in ALTN law, tu abbia deciso di resettare gli ELAC (per inciso dipende da che versione del software monta l'aereo, su quelle più vecchie è possibile farlo in volo, su quelle più recenti è proibito), con lo scopo non di tornare all'atterraggio, chiamare i tecnici e capire che cavolo stia succedendo ma di continuare a fare base training con altri allievi. Se poi, oltre a sfasciare l'areo, si fosse fatto molto male qualcuno o peggio, le conseguenze sarebbero state ancora più pesanti.
Intorno a noi ci sono operatori che fanno cose ad cazzum e va detto, perché bello tutto, bello il mercato libero e bello pagare poco ma certe "pratiche" vanno stigmatizzate perché le regole del gioco vanno rispettate da tutti.
