The National Transportation Safety Board has released its preliminary report on the FedEx landing gear incident in Chattanooga, Tennessee.
In the six page document, it highlights the events that occurred in the cockpit leading to the emergency landing, as well as some other elements within the incident.
Without further ado, let’s get into it…
Recap of the Events in Chattanooga, Tennessee…
The incident involving FedEx flight 1376 from Chattanooga happened on October 4 at 2347 local time when the aircraft experienced a failure with it’s left hydraulic system shortly after departure.
Crew operating the flight stated there was no maintenance issues with N977FD, the aircraft involved in this landing.
After departure at 2224 local time, the crew retracted the landing gear and put the flaps up, to which a message came through saying “TE FLAP DISAGREE”.
Upon completing the checklists, they were able to retract the flaps, but from there, that is when the warning messages about a left-hand hydraulic failure came into play.
Following another series of checklists, the FedEx flight from Chattanooga asked Air Traffic Control if they could do a flypast of the airfield to see whether the landing gear was retracted or not.
When they completed such a flypast, information was relayed to them that the gear was not in the down position, and that the “GEAR UNSAFE” portion of the checklist had to be completed.
From there, they were cleared to land on Runway 20 into Chattanooga, where the aircraft bounced slightly upon touchdown, but were able to keep the aircraft controlled.
N977FD eventually came to a stop around 830 feet beyond the runway, impacting some localizer antennas on the way. You can see a video of this below:
NTSB To Investigate Certain Aircraft Parts on the FedEx Flight…
The NTSB has said that it will be examining some parts of the FedEx Boeing 757 from the incident in Chattanooga following the release of this preliminary report.
It is understood that the left main landing gear door actuator retract port hose was leaking hydraulic fluid, as you can see below:
The report states that the hose was removed and retained by the NTSB for further investigation, with the initial examination showing a discontinuity in the wiring of the landing gear alternate extension system.
It is unclear at this stage what they are looking for as a result of this additional investigation needed, and will no doubt be included in the full report, of which no timescale has been given for this.
Looking ahead, all eyes will be on the investigatory body to see what the contents of the full report regarding the FedEx Boeing 757 incident in Chattanooga.
As soon as that is released, AviationSource will present this in due course.
