Emilio Corsetti concluded that the yaw damper failure caused the lower rudder to go into the hardover position and send the plane into an uncontrollable dive. Then when the landing gear was lowered, the overextension of the right main gear ruptured System A hydraulics that caused the lower rudder to center due to a loss of hydraulic pressure which allowed the crew to recover from the dive. Analysis showed the No. 7 slat was misaligned, showed a lack of wear, and didn't lock into its locking mechanism and was kept retracted by hydraulic pressure and aerodynamic loads. With the loss of hydraulic pressure, the aerodynamic loads caused the slat to extend at 8,000 feet and was quickly ripped off. After landing, hydraulic fluid was observed leaking from the lower rudder actuator; both yaw dampers were removed and replaced but were not inspected for any faults. Therefore, the rudder was what caused the upset, not the slat.

In "Terror Over Michigan", it does show the Flight Engineer declaring they have a flag for the lower rudder yaw damper after they recover from the dive. In the last 30 seconds of the episode it says the pilots maintained their innocence in that they did not extend the flaps and slats mid-flight with Captain Gibson taking it to the grave with him in 2015, and the Lead Flight Attendant interviewed says after a great deal of thought will never know what happened.

 Not done: Per, IMDB, the information is currently correct. Heartmusic678 (talk) 14:51, 8 November 2021 (UTC)[reply]

Crash of the Century should be added back, since it's been uploaded as a Mayday episode on MULTIPLE OFFICIAL Youtube Channels.

https://www.youtube.com/watch?v=_RBLM6qO0g0 https://www.youtube.com/watch?v=JJVrW9UGnrw On top of that, IMDB lists it as such https://www.imdb.com/title/tt4871964/ , it passes the Google Test and Common Name test, and while I couldn't find a copy myself it is apparently on the Mayday DVD.

I agree it's not part of any standard SEASON, as it was produced seperately, but It's clearly considered part of the series Mayday/Air Crash Investigation by official parties, and should this be added back into the list as a 'special' between S3 and S4 like it was before. — Preceding unsigned comment added by 206.174.216.170 (talk) 18:26, 5 April 2022 (UTC)[reply]

2604:3D09:1F80:CA00:C562:7945:21F8:EB5E (talk) 03:17, 9 April 2022 (UTC) To add to this, another older episode is getting a remake, Pacific Plunge is covering the same crash as Cutting Corners, due to differences between the Canadian and American rights holders. So Crash of the Century being remade doesn't mean anything anymore unless you want to say Cutting Corners isn't a Mayday Episode. In Canada, the Show's original region, Crash of the Century is aired as a Mayday episode with the same VO and opening, and clips from it were used in Mayday episodes in S11 and S12.[reply]

The cause is wrong for Terror Over Michigan

The cause listed for TWA Flight 841 "Terror Over Michigan" is "A leading-edge slat had failed due to the pilots extending the slats at cruising speed."

An author and airline pilot with over 25,000 hours, Emilio Corsetti III, published a book in 2016, Scapegoat: A Flight Crew's Journey from Heroes to Villains to Redemption by Emilio Corsetti III | Goodreads. His theory of what really happened was based on years of research, his own investigation, interviews with the pilots, etc. and he determined the evidence best supported they actually suffered a yaw damper induced lower rudder hardover and the No. 7 slat had nothing to do with the upset. He found that Boeing flew a 727 to 37,000 feet with the No. 7 slat fixed in the extended position and flight tests as well as an earlier flight test proved that the Boeing 727 was perfectly flyable with the slat in question extended and no pilot lost control, even at 39,000 feet; the investigators conducted 118 simulator tests and could not get the aircraft to lose control unless the crew made no corrective action for 17 seconds. To believe the NTSB theory, you have to accept that a flight crew would not take corrective action until the plane was in a 120-degree bank. The episode and the NTSB declare that recovery was only possible when the slat tore off at 8,000 feet, but simulator tests showed the slat would have torn off at no lower than 30,000 feet so why didn't the crew recover earlier? Boeing’s own engineers estimated that the slat actuator, piston, and rod could not sustain an airspeed in excess of 363 knots, which would have meant that the slat, if extended at 39,000 feet, should have been torn from the plane much earlier in the dive. Even though the episode shows the vibrations of extending the flaps at slats at 39,000 matched the vibrations recorded on TWA 841's Flight Data Recorder, they actually weren't even close; there were TWA 841 passengers who were taken up on the tests flights to determine if the vibrations they felt by extending the flaps and slats at 39,000 feet were consistent with what they felt on Flight 841 and they said these weren't the vibrations they felt that night.

Emilio Corsetti concluded that the yaw damper failure caused the lower rudder to go into the hardover position and send the plane into an uncontrollable dive. Then when the landing gear was lowered, the overextension of the right main gear ruptured System A hydraulics that caused the lower rudder to center due to a loss of hydraulic pressure which allowed the crew to recover from the dive. Analysis showed the No. 7 slat was misaligned, showed a lack of wear, and didn't lock into its locking mechanism and was kept retracted by hydraulic pressure and aerodynamic loads. With the loss of hydraulic pressure, the aerodynamic loads caused the slat to extend at 8,000 feet and was quickly ripped off. After landing, hydraulic fluid was observed leaking from the lower rudder actuator; both yaw dampers were removed and replaced but were not inspected for any faults. Therefore, the rudder was what caused the upset, not the slat.

In "Terror Over Michigan", it does show the Flight Engineer declaring they have a flag for the lower rudder yaw damper after they recover from the dive. In the last 30 seconds of the episode it says the pilots maintained their innocence in that they did not extend the flaps and slats mid-flight with Captain Gibson taking it to the grave with him in 2015, and the Lead Flight Attendant interviewed says after a great deal of thought will never know what happened.

The synopsis should say "On 4 April 1979, Trans World Airlines (TWA) Flight 841 enters a spiral dive while en route to Minnesota. "The pilots regain control and make an emergency landing at Detroit, with no fatalities. The cause of the dive remains unknown [or] disputed."
