Occurrence Briefs are concise reports that detail the facts surrounding a transport safety occurrence, as received in the initial notification and any follow-up enquiries. They provide an opportunity to share safety messages in the absence of an investigation.
On 23 March 2019, a Luscombe Aircraft Corp 8A departed Bunbury, Western Australia, to conduct a training flight with an instructor and a student on board. During approach to land back at Bunbury, the aircraft encountered unexpected turbulence and windshear and as a result, the aircraft landed heavily. The crew exited the aircraft without injury and conducted an inspection to check for any damage. The post-flight inspection did not reveal any damage and the aircraft subsequently conducted two more flights.
On 25 March 2019, the aircraft was sent to a Licensed Aircraft Maintenance Engineer (LAME) to conduct a more detailed and thorough inspection. The engineering inspection revealed that the aircraft had sustained substantial damage with some slight creasing at the attach point of one of the undercarriage legs, some dimpling on top of a wing and skin dimpling behind the rear door post. The LAME found the aircraft to be unserviceable and it was consequently grounded.
All pilots, regardless of their experience levels, should be prepared to undertake a go-around rather than continuing with an unstable approach. The Flight Safety Foundation released a briefing note Approach-and-landing accident reduction Briefing Note 6.1 to remind pilots of the importance of being prepared to conduct a go-around during all approaches. This occurrence also serves as a reminder that after any hard landing or other related incidents, where the integrity of the airframe or structure may be compromised, a detailed and thorough engineering inspection should always be carried out to ensure the serviceability of the aircraft and all of its components.
