AA於8/31 這天意外/錯誤的使用無etops之A321 飛航LAX至夏威夷.
簡單說, AA的A321 有兩種型號, 一種是有ETOPS 認證的A321H ; 另外一種則是無ETOPS
認證的A321S
American Airlines accidentally flew the wrong plane from L.A. to Hawaii last
month
In late August, American Airlines accidentally flew the wrong plane from Los
Angeles to Hawaii, a mix-up that violated Federal Aviation Administration
regulations.
The mistake, first reported by aviation blogger Brian Sumers, occurred on
Aug. 31 — just days after the airline began flying Airbus A321 planes on the
L.A. to Hawaii route (other planes in American Airlines’ fleet have long
flown this route).
A spokesman for the airline confirmed to the Washington Post that a version
of the A321 plane that was not certified to make long flights over water —
as on the route between Los Angeles and Hawaii– was accidentally flown that
day.
The mistake was caught midway through the flight, Sumers reported, but a
decision was made to continue to Hawaii. The airline canceled the return
flight and the empty plane was flown back to Los Angeles.
“Immediately when we realize what happened, we notified the FAA and we are
working and fully cooperating with them,” said spokesman Casey Norton. “We
also have an ongoing, thorough review of our policies and procedures.”
Planes that fly routes with no suitable landing areas are required to have a
certification called ETOPS (Extended-range Twin-engine Operational
Performance Standards) which is primarily an administrative requirement, but
it also calls for the planes to be equipped with extra oxygen and a fire
suppression cannister.
The A321 planes can be either ETOPS certified or non-ETOPS certified. Both
planes have the same number life vests, rafts, and engine range, Norton said.
According to Sumers, airlines don’t certify all planes, just the ones that
are used to fly the long-range routes over water:
Obtaining ETOPs certification is not difficult but it is a complicated
process, and so there’s no reason to certify aircraft that won’t fly
on long routes over water. As a result, American has two types of A321s
in its standard first class and coach configuration – the A321H, which
can fly to Hawaii, and the A321S, which cannot.
Yet flying a non-ETOPS certified plane, as American did on Aug. 31, is a big
mistake and it is extremely rare, Norton acknowledged.
Sumers, who writes about aviation issues, said that he first learned about
the mistake from pilots chatting online anonymously.
“It’s really rare,” Sumers said. “Something like this, when you talk to
airline people, they say ‘How does this happen? This can’t happen?'”
