American Airlines A321 Loses Wing Part
An American Airlines flight landing in Charlotte, North Carolina, has been temporarily taken out of service after an inspection revealed that a rivet was missing from one of the wing slats. The Airbus A321-200 completed its flight on August 10th without incident, and the missing part was only discovered after it landed. The plane was taken out of service and remained grounded for over 12 hours after the discovery.
Missing screw or missing slat?
The American Airlines flight AA-1642 from Detroit, Michigan, to Charlotte, North Carolina, landed safely after 85 minutes in the air. The plane landed just 15 minutes behind schedule and did not report any incident while in the air. However, upon a post-flight inspection, the Airbus A321-200, registration N198UW, was found to have a rivet missing from a wing slat.
The aircraft in question was taken out of service, although supposedly for an unrelated issue. The Aviation Herald is reporting that a source confirmed that rather than a screw missing, the entire slat had gone. However, an American Airlines representative confirmed to Simple Flying that “It was one small rivet that was missing. Early reports were false.” The representative also confirmed that the aircraft is now back in service.
A321 wing slats
Slats are extendable and retractable devices fitted to the leading edge of aircraft wings. The slats are designed to give an extra lift to an aircraft during low-speed maneuvers such as takeoff, approach, and landing. The slats are deployed hydraulically or using electrical switches.
The Airbus A321 aircraft has five slats on each wing. While it may not seem too severe for a screw to be loose, or indeed for one of five slats to be missing, the slats help pilots control the aircraft when landing. A slat in the wrong place changes the flow of air over the wing resulting in an imbalance and can cause serious problems with the landing procedure. Luckily, the American Airlines flight landed safely.
