On 6 November 2022 adverse weather delayed an ATR42 beginning its visual-only approach to Bukoba. When an approach was commenced, adequate visual reference was not maintained due to continued adverse weather. No corrective action was taken in response to three successive automated excessive descent rate alerts or the first officer’s calls to reduce descent rate. Although response did follow a ‘PULL UP’ warning, it was too late to prevent a high-energy impact with the surface of Lake Victoria close to the shoreline, and both pilots and 17 of the passengers were killed.
Description
On 6 November 2022 an ATR 42-500, (5H-PWF) operated by Precision Air on a scheduled domestic passenger flight from Dar es Salaam to Bukoba as PW494 encountered adverse weather at the visual approach-only destination. After a short delay, the captain decided to commence a visual approach to Runway 31 in day instrument meteorological conditions (IMC). The prevailing weather was not conducive to this. Below 500 feet, after EGPWS ‘SINK RATE’ alerts were ignored despite the first officer’s calls to reduce rate of descent, an EGPWS ‘PULL UP’ warning followed. This was followed by a nose-up input on the control column, but it was too late to prevent a hard impact with the surface of Lake Victoria close to the runway threshold. This severely damaged the aircraft and rendered it beyond economic repair. Seventeen of the 39 passengers on board were killed as were both pilots. There were no serious injuries to the 24 occupants who survived and only one minor injury to one of the cabin crew.
