FedEx 1420 - tailstrike at DEN
FedEx 1420 reports a hard landing and potential tailstrike at Denver International Airport.
Summary
FedEx 1420, a heavy cargo aircraft, experienced a hard landing on Runway 17 Right at Denver International Airport. After the landing, air traffic control inquired about a possible tailstrike, leading the pilot to confirm a "hard hit" and request a runway inspection. The incident resulted in the immediate closure of the runway and the diversion of following traffic.
Analysis
This recording captures the immediate aftermath of a tailstrike incident involving a FedEx heavy aircraft (likely an MD-11, given the flight number and aircraft's reputation for sensitive landing pitch). A tailstrike occurs when the aft fuselage of an airplane contacts the runway during takeoff or landing. In this case, the controller noticed something unusual enough to proactively ask the pilots if a tailstrike was "possible." The pilots admitted to a "hard hit," which is a significant admission in aviation, indicating the landing forces exceeded normal parameters.
The exchange is a textbook example of airport safety procedures. Once a tailstrike is suspected, the runway must be closed immediately for a "FOD" (Foreign Object Debris) inspection. This is crucial because a tailstrike can shave off metal, break light fixtures, or leave structural components on the runway, which could be ingested by the engines of a subsequent aircraft. The recording shows the Tower controller coordinating with "Ops 7" (Airport Operations) to shut down the runway within seconds of the landing.
For non-experts, it is notable how calm the pilots and controllers remain. Despite the potential for significant structural damage to a multi-million dollar aircraft, the communication remains professional and focused on the safety of other flights. The controller quickly redirects the following aircraft, FedEx 1728, to an adjacent runway to maintain the flow of traffic while the primary runway is inspected.
The significance of this event lies in the MD-11's history; the aircraft is known for being difficult to land due to its high approach speed and sensitive elevators. Tailstrikes on this airframe often require extensive structural repairs and inspections of the rear pressure bulkhead to ensure the aircraft remains pressurized and airworthy in future flights.
