The pilot of a kit-made mild plane that crashed in Gippsland simply over a yr in the past was identified for “dangerous flying behaviour” and had obtained “insufficient” coaching, the ATSB has concluded.
All three occupants of the experimental Morgan Cougar Mk 1, VH-LDV – 20-year-old pilot Luke Smith; his youthful brother Ben, 16; and cousin Dusty Daly, 15 – had been killed when it crashed right into a paddock close to West Sale Airport on 16 November 2024.

In accordance with eyewitness accounts, CCTV footage, flight knowledge, and examination of the location and wreckage by the ATSB, the plane went into an accelerated stall throughout a steep flip throughout the native space flight.
“The stall occurred throughout the third orbit over the realm, the bottom and slowest of the three,” mentioned ATSB chief commissioner Angus Mitchell.
“Because the plane turned steeply to the left it entered a stall, at a top too low to recuperate.”
Smith, who had obtained his CASA-approved pilot’s licence three months earlier than the accident based mostly on his Leisure Aviation Australia (RAAus) leisure pilot certificates from Journey Flight Coaching, had a “reported historical past of conducting low flying and gradual steep turns”, the ATSB mentioned.
“The investigation revealed a pattern of dangerous flying behaviour by the accident pilot, which was seemingly compounded by insufficient data from a flight coaching college that had developed irregular practices within the supply of coaching and had insufficient supervision,” mentioned Michell.
“Whereas many individuals knew of the pilot’s dangerous flying behaviour and had tried to counsel them, there was no proof that any of the incidents had been reported to authorities, and the counselling efforts had been finally unsuccessful.
“As well as, the plane was newly acquired by the pilot, and so they had not obtained transition coaching, so had been seemingly unaware that, whereas the accelerated stall traits of the accident plane had been unknown, there have been indications that it will be abrupt.”
As a part of its investigation, the ATSB interviewed “a number of events” concerned with the Journey Flight Coaching flying college, which had closed in August 2024, three months earlier than the accident, following a safety-related suspension discover towards its chief flying teacher.
Particularly, a have a look at Smith’s examination historical past revealed “a number of errors about aerodynamic stalling in exams performed throughout 2024, and it was concluded the pilot seemingly had insufficient data of the connection between angle of financial institution, load issue and stall pace,” the ATSB mentioned.
“These accounts, in addition to an examination of obtainable information, recognized a collection of irregularities with the best way the college educated and examined its pilots for certification,” mentioned Mitchell.
“The ATSB discovered RAAus had insufficient controls to mitigate the irregular examination practices recognized on the flying coaching college.”
Whereas RAAus had additionally issued safety-related suspensions towards all Journey Flight Coaching graduates for “potential data deficiencies”, CASA did not test if any of these graduates had used their RAAus certificates to achieve CASA licences.
“It was subsequently discovered that two extra pilots held a CASA-issued licence, granted based mostly on the RAAus certificates that they had earned on the Journey Flight Coaching college,” mentioned Mitchell.
Moreover, the ATSB discovered that the plane itself had “design deficiencies” which made the crash extra extreme, however CASA’s steering materials for amateur-built experimental plane “doesn’t suggest consideration of the crashworthiness of seating and gas tank set up”.
“These points included an absence of power attenuation within the touchdown gear and seating, and the set up of a gas tank between the engine and instrument panel that ruptured and brought about the post-crash hearth,” mentioned Mitchell.
“Given the significance of power attenuation for crashworthiness, and the susceptibility of plane gas tanks to rupturing, the ATSB concluded that the amateur-built business may gain advantage from further steering in these areas.
“These traits inside the design of the plane, on this case, elevated the chance of occupant accidents, and I’d urge novice builders and designers to contemplate these components for their very own plane.”
Each CASA and RAAus have since up to date their programs and procedures, together with a web based examination system at RAAus, and extra sturdy processes round studies of suspensions, variations or cancellations of authorisations at CASA.
