ULC: In mid-January published guidance on recovering B737 MAX – Puls Biznesu

At the end of November, the European Union Aviation Safety Agency (EASA) published a draft proposed Airworthiness Directive (PAD) for the Boeing 737 MAX. It was then announced that comments could be submitted on the draft during the 28-day consultation period. After this time, before publishing the final version of the guidance, EASA will analyze the comments received.

“The Civil Aviation Authority has actively participated in all the conferences relating to the return of the B737 MAX to work, organized by both EASA and the US Federal Aviation Administration (FAA). The CAA has not commented on the draft EASA PAD Airworthiness Directive with respect to the return of aircraft to service. 737-8 and 737-9 “- ULC informed the Pan-African Parliament.

The authority announced that the final version of the document will be published in mid-January 2021. The Civil Aviation Authority said: “It will constitute an official decision to return all 737 MAX aircraft that are held by operators from EASA member states.”

Max in its fleet is PLL LOT – five aircraft and Enter Air – two B737 MAX8.

According to the CAA, according to the draft EASA Airworthiness Directive, before individual airlines can re-include aircraft in the flight schedule, airlines will have to update the software and perform maintenance work specified in the final version of the Airworthiness Directive. They also need to train their pilots to fly the 737 MAX. Due to the limited number of flight simulators, this may take some time. Some of that work could begin now, even before the final version of the Airworthiness Directive is published.

The guidance project also requires measures such as, among other things, modernization of the flight control computer software, physical separation of the cables leading from the cockpit to the stabilizer trim system; Flight guide update: operational constraints and procedures revised so pilots understand and deal with emergency scenarios.

The proposed directive also provides for a test flight, without passengers, before each of these aircraft is used for commercial flights, to ensure that all changes are properly made and that the aircraft is safely re-escaped after a long hiatus.

“ The proposed EASA Airworthiness Directive requires the same changes as the FAA, so there will be no differences in software technology between US aircraft and those flying in EASA member states (27 EU member states, Iceland, Liechtenstein, Norway and Switzerland until December 31) 2020, the UK will also be treated as a member state of the European Union ” – stated the Civil Aviation Authority.

The Boeing 737 Max was stopped by EASA on March 12, 2019 after two accidents with these machines – in Indonesia in October 2018 and in Ethiopia in March 2019 – in which a total of 346 people were killed.

According to the Civil Aviation Authority at the end of November, “the extensive work done by 20 EASA experts over the past 20 months has assured the agency that Boeing 737 MAX aircraft are safe and can return to flight operations.”

The Civil Aviation Authority reported at the time that investigations into both accidents showed that the main cause of each was the function of the Maneuvering Characteristics Enhancement System (MCAS), which was to facilitate the aircraft’s maneuverability. However, the MCAS, which is guided by only one corner of the attack sensor, is continuously triggered as if the sensor were malfunctioning, pushing the nose of the aircraft down several times and ultimately preventing the aircraft from being controlled. This was the cause of both incidents.

The U.S. Federal Aviation Administration (FAA), Boeing’s design state, released final approval of the revised 737 MAX in the Federal Register on November 20, 2020.
