The capture of a veteran American Airlines repairman this week for supposedly disrupting a plane at Miami International Airport an hour prior to departure in July started judgment by the airline and its mechanics association Friday — and raised disturbing wellbeing worries for voyagers.

Also, there was a noteworthy new advancement: the 60-year-old specialist was terminated from Alaska Airlines 10 years prior, after a progression of "stumbles that prompted numerous FAA examinations'' and later ineffectively sued the airline for separation, as indicated by a report by Business Insider.

The Frozen North representative Ray Lane affirmed Abdul-Majeed Marouf Ahmed Alani was a flight specialist and line flying expert who worked for Seattle-based Alaska from January-August 1990 and again from June 1998-July 2008. He declined to remark on his work force record or purpose behind leaving.

Those dates cover with his work at American, which he participated in 1988 and was situated in Miami, so it's indistinct how he held the two occupations or whether American knew his activity history. The airline does not preclude representatives to hold two employments, with certain special cases.

In a letter to representatives, the world's biggest airline called Alani's supposed altering of a Boeing 737-800 destined for the Bahamas with 150 individuals on board a "very genuine'' episode and said it was "aggravating and disillusioning to us all.''

Senior Vice President David Seymour proposed, however, that such altering was an uncommon event.

"The charges include one person who bargained the security of one of our airplane,'' he said in the letter. "Luckily, with suitable wellbeing conventions and procedures, this present person's activities were found and moderated before our flying machine flew.''

The TWU/IAM Association, which has been secured hostile contract dealings and a fight in court with American over what the airline calls an illicit work activity this mid year, denounced the episode. Alani told examiners he obstructed a key PC framework to compel the deferral or scratch-off of the flight since he was vexed about the slowed down contract exchanges and said it hurt him monetarily.

An announcement marked by affiliation executive Sito Pantoja and bad habit chief Alex Garcia says:

"The TWU/IAM Association censures, in the most grounded potential terms, any lead by any person that imperils the protected activity of a flying machine security is the main need for our IAM and TWU individuals engaged with the upkeep and activity of air ship. These individuals are the most profoundly prepared security experts in the airline business. Thus, the US air transportation framework is the most secure on the planet. Any direct that risks that wellbeing isn't endured or excused by the administration or individuals from our associations.''

How easy is it for an airline employee to tamper with a plane?
"The ease of access is definitely there,'' said Bill Waldock, professor of safety science at Embry-Riddle Aeronautical University in Prescott, Arizona.

Mechanics and pilots walk around planes every day before and after flights to work on or check out the aircraft. All are certified by the Federal Aviation Administration and go through a background check.

"These are the people who maintain the airplane, who fly the airplane,'' said John Cox, a retired US Airways captain who runs aviation safety consulting firm Safety Operating Systems and writes USA TODAY'S Ask the Captain column. "It's very appropriate, it's very necessary, it's essential that they have access to the airplane.''

Waldock said airlines have plenty of security and backup security and checks and balances, including quality assurance workers, to oversee work.

Alani wasn't working his normal shift or station. Why didn't anyone notice?
According to the criminal complaint against Alani in U.S. District Court in Miami, the mechanic should not have been working on a panel on the nose of the plane because there was no report of a mechanical issue there, nor a pending work order, American told law enforcement officials.

Two more red flags: He normally works on disabled aircraft in the maintenance hangar at Miami International, not on planes at the gate. And his shift was generally from 10 p.m. to 6:30 a.m., the airline said. He worked that shift on July 16 and then switched shifts to work the morning shift the next day, the day of the incident, working until 2:30 p.m., American told investigators. He worked a double.

Cox said there are so many moving parts on the aircraft ramp that Alani, a veteran worker, might have appeared as if he was simply doing his job. Cox walked around planes every day with a different to-do list and few second looks.

"The people around (me) don't know what I'm doing,'' he said. "You vet and train the individuals and you expect them to do the job that they're supposed to do.''

American hasn't commented on any specifics beyond its statements. Alani was been suspended from American after his arrest, American spokesman Ross Feinstein said.

There were 150 people on board Flight 2834. Were they in danger?
Scary as a disabled computer system on a plane about to take off sounds, Waldock and Cox insist passengers were never in danger because the blocked air data module (ADM) set off immediate warnings in the cockpit during a routine pre-departure check.

"It's easily detectable because they're going to get a big error message on the front of their screens on the instrument panel,'' Waldock said. "It would tell them that the system isn't functioning properly.''

That sends the plane back to the gate, which is what happened with Flight 2834.

"This is a very unfortunate action of a disgruntled individual, but it did not put people at risk because of the design of the airplane and the training of the pilots to make sure that all the systems are functional prior to flight,'' Cox said.

In the unlikely case the error didn't flash or wasn't detected until the flight was airborne, there are backup systems that would kick in, Waldock and Cox said.

"There's a standby set of instruments completely isolated from that whole (ADM) system that are intended to give you just enough information to be able to fly the airplane,'' Waldock said.
