Chalk & Cheese: ATSB v TSBC?? - 

Recently from PJ central media HQ, the man himself Popinjay popped in to give his profound wisdom and experience in Aviation Accident Investigation to be attributed to the following propaganda fluff piece on a 'Short' (sadly fatal -  ) preliminary report into a Chipmunk collision with terrain accident at YPJT on the 26 April 2024 (40 days in non-compliance with ICAO Annex 13 time limitations for a prelim report) -   :

Jandakot Chipmunk aircraft accident preliminary report

A preliminary report details evidence gathered to date by the ATSB from its ongoing investigation into an accident involving a Chipmunk aircraft at Perth’s Jandakot Airport on 26 April 2024.

ATSB investigators deployed to Jandakot after the DHC-1 Chipmunk, a former military pilot training aircraft, collided with the ground within the airport boundary shortly after take-off.

The pilot, who was the sole occupant, sustained fatal injuries in the accident.

Prior to the accident, the aircraft had been taxied by the pilot from Jandakot’s southern apron to the end of runway 24L, the report details.

“A witness on the southern apron took photographs of the aircraft taxiing past, and these show the latches on the left side engine cowl were oriented vertically,” Chief Commissioner Angus Mitchell said.

The Chipmunk’s left and right engine cowling doors are each secured by two latches. The latches fasten the doors when they are in the horizontal position, and the doors are unfastened when the latches are vertical.

After the pilot was given clearance, they began the take-off roll, and the aircraft became airborne about halfway along the runway.

“One witness recalled seeing something ‘flapping’ on the aircraft during the take-off,” Mr Mitchell explained.
That witness, and others in a nearby building, observed the aircraft roll to the left at low height near the end of runway 24L.

“Camera footage showed the aircraft’s angle of bank increasing and the aircraft descending into terrain. A camera about 180 m to the south-east of the accident site recorded the engine cowling on the left side opening and closing in the seconds prior to the accident.”

ATSB investigators’ wreckage examination noted damage to the engine cowl latches indicative of their being correctly fastened on the right side and unfastened on the left.

“All major aircraft components were accounted for, witnesses had not reported any change in engine sound prior to the accident, and the propeller showed evidence that the engine was running at impact,” Mr Mitchell said.

ATSB examination established continuity of the aircraft’s flight controls, and the flaps were assessed to have likely been in the retracted position at time of impact.

As the investigation progresses, the ATSB will conduct further examination of the aircraft components, review aircraft and pilot documentation, and analyse the aircraft’s flight path, and impact forces.

A final report, which will detail analysis and the ATSB’s findings, will be released at the conclusion of the investigation.

“Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate and timely safety action can be taken,” Mr Mitchell concluded.

Keep in mind this is only a prelim report into a relatively straight forward pilot error 'Short' investigation, so why does Popinjay feel the need to sign off on 'attributed' to him quotes that are pretty much taken directly from the prelim report?

EG:

PJ said: “A witness on the southern apron took photographs of the aircraft taxiing past, and these show the latches on the left side engine cowl were oriented vertically,”

Report said: ..A witness on the southern apron took photographs of the aircraft taxiing past, which show the engine cowl latches on the left side were oriented vertically..

PJ said: “One witness recalled seeing something ‘flapping’ on the aircraft during the take-off,”

Report said: One witness, located at the run-up bay, recalled seeing something ‘flapping’ on the aircraft during the take-off.

PJ said: “Camera footage showed the aircraft’s angle of bank increasing and the aircraft descending into terrain. A camera about 180 m to the south-east of the accident site recorded the engine cowling on the left side opening and closing in the seconds prior to the accident.”

Report said: ..The camera footage showed the aircraft’s angle of bank increasing and the aircraft descending before colliding with terrain. A camera at a building about 180 m to the south‑east of the accident site recorded the engine cowling on the left side opening and closing in the seconds prior to the aircraft’s collision with terrain (Figure 3)...

Now compare that waffle and regurgitated piffle; to the following TSBC Final Report into another pilot error terrain collision accident involving a flight training pilot on his 1st solo circuit in a C152:

Loss of control and collision with ground

Orizon Aviation Québec Inc.
Cessna 152, C-FNBP
Québec/Jean Lesage International Airport, Quebec

The occurrence
On 01 August 2023, an Orizon Aviation Québec Inc. Cessna 152 aircraft was on a local training flight, with one pilot on board.

Upon landing at the Québec/Jean Lesage International Airport (CYQB), Quebec, the aircraft bounced and veered off the runway to the south, and then became airborne again. As the aircraft climbed, the left wing stalled, and the Cessna collided with the ground.

The pilot was seriously injured. There was no post-impact fire.
