Screwdriver tip left in engine during maintenance results in engine failure on take-off

An engine power loss and rejected take-off incident involving an Airbus A320 at Brisbane Airport occurred after a screwdriver tip was left inside the engine during maintenance, an Australian Transport Safety Bureau investigation notes.

On 23 October 2020, the Jetstar Airways operated A320 was departing on a scheduled passenger flight from Brisbane to Cairns.
As power was being applied for take-off, the crew felt a vibration and heard a popping noise, which rapidly grew faster and louder. At the same time, the aircraft diverged to the right of the runway centreline despite the first officer applying full left rudder pedal.
The captain immediately selected reverse thrust and brought the aircraft to a stop.

Some of the passengers onboard the aircraft, a Brisbane tower air traffic controller, and flight crew of a following aircraft reported momentarily seeing flames coming out of the right engine.

The aircraft was taxied back to the airport gate, and all passengers and crew disembarked safely.

Engineers then reported finding metallic debris in the tailpipe of the aircraft’s right engine. On disassembly, it was discovered the engine’s high-pressure compressor had sustained significant damage. A removable screwdriver tip was found in the engine’s combustion section.

The ATSB’s investigation determined the screwdriver tip had been in the engine for over 100 flights.

The liberated blade then caused greater damage to the engine’s high pressure compressor, and the engine surged, resulting in the loss of power and the low-speed rejected take-off.

Poor braking conditions after heavy rain led to 737 runway overrun, Jacksonville

A Miami Air International Boeing 737-800 overran a rain-soaked runway due to an “extreme loss of braking friction,” the NTSB concluded in its investigation report (PDF).

Miami Air International flight 293, a Boeing 737-800 charter transporting U.S. Department of Defense personnel from Guantanamo Bay, Cuba, ended up in shallow waters of the St. Johns River after it overran runway 10 at Jacksonville Naval Air Station, Florida, while landing in a heavy rainstorm May 3, 2019. Although none of the 143 passengers and crew onboard were seriously injured, several animals carried in the cargo compartment died in the accident.

The accident report details how the flight crew did not follow procedures, including continuing an unstabilized approach, landing the airplane at an excessive approach speed, and delaying deployment of the speedbrakes. However, investigators determined that even if none of those errors occurred, the airplane still would not have stopped on the ungrooved runway because the rainfall rate and runway characteristics contributed to water depths that caused the aircraft to hydroplane.

The investigation also found Miami Air International failed to provide its flight crews with adequate guidance for evaluating braking conditions for landing on wet or contaminated runways.

Miami Air International ceased operations May 8, 2020.
