As jets return from pandemic storage, Airlines warned over safety

SYDNEY: Regulators, insurers, and consultants are warning airlines to take extra care when reactivating planes left in extended storage throughout the COVID-19 pandemic, citing potential pilot rustiness, maintenance errors, and even insect nests blocking key sensors.

The unprecedented number of planes grounded as coronavirus lockdowns blocked air travel – at one level reaching two-thirds of the global fleet – has created a spike in the variety of reported issues as airlines return them to service.

The number of “unstabilized” or poorly handled approaches has risen sharply this year, in keeping with the International Air Transport Affiliation (IATA). Such mishaps may end up in hard landings, runway overshoots, or even crashes.  

Apprehensive by IATA’s information, insurers are questioning airlines about whether or not they’re doing extra pilot coaching to deal with landings, mentioned Gary Moran, head of Asia aviation at insurance coverage dealer Aon PLC.

“They wish to know about the circumstances of the coaching,” he mentioned.

Approaches and landings place vital demands on the crew for which coaching and common expertise are seen as very important.       

In response to plane maker Airbus, the largest class of deadly accidents might be traced again to the strategy to an airport, whereas the most important variety of non-fatal accidents occur throughout landing.

In Could, a Pakistan International Airlines jet crashed after an unstabilized approach, killing 97 people, whereas 18 died in an Air India Categorical crash on landing in August, also after an unstabilized strategy.


Coaching will not be the one concern.

The European Union Aviation Safety Agency (EASA) has reported an “alarming pattern” within the variety of reviews of unreliable airspeed and altitude readings throughout the first flight after an airplane leaves storage.

In some circumstances, take-offs needed to be deserted or the plane needed to return to base.

Usually, the problem was traced again to undetected insect nests contained in the plane’s pitot tubes, pressure-sensitive sensors that feed key information to an avionics computer.

In June, a Wizz Air jet halted take-off after the captain discovered the airspeed was studying zero.

Examination of the airplane discovered insect larvae in one of many pitot tubes, with the plane having been parked for 12 weeks earlier than the flight, the UK Air Accidents Investigation Department said final month. No passengers were on board.

Bugs blocking a pitot tube contributed to the 1996 crash of a chartered Birgenair airplane in the Dominican Republic that killed all 189 people on board.

Kate Seaton, a Singapore-based aerospace companion at regulation agency HFW, mentioned flight crews want to be aware of potential defects that might not have been recognized properly as planes return to service after an unprecedented grounding.

“We’re in new territory – the industry should take steps to mitigate the dangers however must be ready for the sudden,” she mentioned.


EASA mentioned the final month that points discovered after extended parking included an engine shutdown in flight after technical issues, gas system contamination, reduced parking brake stress, and emergency batteries shedding their cost.

“We have people returning to work who’re quite rusty, which is a big challenge,” insurer Aon’s Moran mentioned.

Airlines have developed coaching programs for pilots re-entering service ranging from principle refreshers to multiple simulator periods and supervised in-flight checks, relying on the size of absence.

Australia’s aviation regulator mentioned on Nov 30 its inspectors would beef up surveillance on COVID-19 associated risks involving the re-entry into service, pilot coaching, and safety risk management for the rest of the yr by means of Jun 30, 2021.

Pilots also have to make a trustworthy assessment of their skills and confidence upon returning to work, International Federation of Air Line Pilots’ Associations consultant Peter Meiresonne mentioned at a trading webinar in October. They could want to showdown gives like shorter touchdown approaches from air traffic management if they don’t really feel prepared, he mentioned.

“Possibly now is an efficient time to say, ‘We’re not ready today’ or ‘Give us a six- or 10-mile lineup slightly than a four-mile lineup’, which you may settle for when you’re more proficient and (flight expertise is) more modern,” he mentioned.
