united airlines flight 173 air crash investigation

That unusual sound was accompanied by abnormal vibration and "The Safety Board believes that this accident exemplifies a recurring problem—a breakdown in cockpit management and teamwork during a situation involving malfunctions of aircraft systems in flight… Therefore, the Safety Board can only conclude that the flightcrew failed to relate the fuel remaining and the rate of fuel flow to the time and distance from the airport, because their attention was directed almost entirely toward diagnosing the landing gear problem. See if we get gear lights.” The flight engineer complied with the request.At 1810:47, the captain requested the flight’s distance from the airport. McBroom had been with United Airlines for 27 years; he was one of the airline's most senior pilots with more than 27,600 hours of flight time, of which about 5,500 hours had been as a DC-8 captain.

In late December 1978, a United Airlines commercial aircraft DC-8 carrying 181 passengers and 8 crew crashed outside Portland, Oregon. This new type of training addressed behavioral management challenges such as poor crew coordination, loss of Assigned to investigate this accident, Diehl realized it was similar to several other major airline accidents including Held responsible for the accident, Captain McBroom lost his pilot's license and retired from United Airlines shortly afterwards. The crew requested a holding pattern to diagnose the problem, and for approximately the next hour the crew flew over southeast Portland and worked to identify the status of the landing gear and prepare for a potential emergency landing. Flight 173 was piloted by an experienced cockpit crew, consisting of Captain Malburn "Buddy" McBroom (age 52), First Officer Roderick "Rod" Beebe (45), and Flight Engineer Forrest "Frosty" Mendenhall (41). Transcripts of cockpit recordings confirm this.Issue an Operations Alert Bulletin to have FAA inspectors assure that crew training stresses differences in fuel-quantity measuring instruments and that crews flying with the new system are made aware of the possibility of misinterpretation of gauge readings. The first officer and flight engineer had over 2,500 hours of flying experience between them in the DC-8.As the landing gear was being lowered on approach to Portland International Airport (PDX), the crew felt an abnormal vibration and yaw of the aircraft as well as a lack of an indicator light showing the gear was lowered successfully. #LIFT https://twitter.com/engineers_feed/status/1250296463256481793 We can’t make Troutdale.”  The first officer said, “We can’t make anything.”At 1813:46, the captain told the first officer, “Okay. From the NTSB recommendations:Initially identified as Flightdeck Resource Management, this concept quickly evolved to Cockpit Resource Management. Happy Father's Day to @AstroBehnken, @AstroDoug, @Astro_SEAL and Anatoly Ivanishin! (Eds.). For this reason, they recommended that additional training and a bulletin of this issue be released to all aircrew operating on the DC-8.More importantly for the future safety of aviation, however, was the NTSB’s recommendation for a totally new type of training.

During this time, none of the three cockpit flight crew effectively monitored the fuel levels, which was exacerbated by the fact that the gear was down with the flaps at 15 degrees during the entire hour-long holding maneuver, significantly increasing fuel burn rate. @TSA temporarily increased the amount of hand sanitizing products you may bring in your carry-on bag, up to 12 fl. oz.

By the time this was realized, reaching Portland International had become an impossibility.At 1809:21, the captain advised Portland Approach, “United, seven three is going to turn toward the airport and come on in.”  After confirming Flight 173’s intentions, Portland Approach cleared the flight for the visual approach to runway 281.At 1810:17, the captain requested that the flight engineer “reset that circuit breaker momentarily. and the Defense Department have teamed to build a national training and support network calling for the National Implementation of

"The failure of the captain to monitor properly the aircraft's fuel state and to properly respond to the low fuel state and the crewmember's advisories regarding fuel state. Did you know we've got four dads in space? Their fuel quantities were known throughout the series of events and the time and distance able to be traveled with diminishing fuel was predictable. In late December 1978, a United Airlines commercial aircraft Here is the summary abstract from the official NTSB report:Although the pilot’s abilities to land the DC-8 in a populated suburban area with minimal loss of life should be lauded, the unfortunate event could have almost certainly been avoided if the pilot-in-command and his crew had worked together more effectively.

CRM was first adopted (not surprisingly) by United Airlines in 1981 and is now a mandatory part of crew training for most major airlines, NASA and military aviation. We’re–the engines are flaming out.
