Alaska Airlines incident: What one pilot was surprised by

Boeing (BA) shares began to dip after a door plug blew out on a Boeing 737 Max 9 jet being flown by Alaska Airlines flight (ALK). The flight was able to return safely without harm to any passengers on board. Many questions arise around how this situation occurred, including was there anything Boeing and Alaska Airlines could've done to prevent it.

Anthony C. Roman, FAA licensed commercial pilot and Founder & CEO of A.C. Roman and Associates joins Yahoo Finance to discuss the incident and what precautions could have potentially been taken.

Roman discusses what the public has learned about the plane, saying "What surprises me here is that this incident occurred several times, including depressurization problems, just the day prior to the accident. I'm surprised that Alaska Airlines did not ground their Max 9 fleet and conduct a thorough inspection of all of the aircraft to see if it could be replicated."

Video transcript

RACHELLE AKUFFO: A horrible experience for those on the flights. But what about the wake up calls in terms of the training that's needed and the investigations needed to really secure these planes?

ANTHONY ROMAN: Well, I think that the flight crew performed superbly, frankly. They were disciplined, the flight attendants whose primary responsibility is certainly not serving food or helping you find your seat. It certainly is safety. Safety first and coordinating the emergency procedures when an incident like this happens.

In this case, the recordings reflect that the flight attendants performed superbly and probably saved many passengers. The flight crew performed as expected, professionally, communicating with air traffic control, and descending at a proper descent rate and landing the plane successfully.

Missing a door can control-- can cause some control difficulties, flutter on the empennage which creates shaking of the controls in the cockpit and other difficult maneuvering type of problems. So the flight crew, superb.

RACHELLE AKUFFO: And you certainly have to have nerves of steel in that sort of environment where everything is happening and it's so loud and, as you mentioned, almost an explosive sort of environment when something like that happens.

So I do want to ask you then about some of the warning signals because we're seeing reports that there were some concerns about depressurization issues with this aircraft. How difficult is it for staff to really voice concerns and have them addressed properly?

ANTHONY ROMAN: Well, it's procedural. And believe me, the flight crew, when they see pressurization problems in that type of aircraft or any type of aircraft, the first thing they are going to do is run their checklist. And then if that doesn't resolve the problem, notify the mechanics. And have it inspected prior to flight.

What surprises me here is that this incident occurred several times, including depressurization problems just the day prior to the accident. And I'm surprised that Alaska Airlines did not ground their Max 9 fleet and conduct a thorough inspection of all of the aircraft to see it could be replicated.

What they did do I think was very limited in nature. They prohibited Alaska Airlines Max 9s from overwater flight. A good judgment. But I don't think that it was sufficient given what happened on this plane several times.
