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 22 November 2018 a Cessna 210 was conducting a freight charter flight to Kilarney Station, Northern Territory (NT). The pilot was the sole occupant on board.
During approach to Kilarney Station, the landing gear failed to extend. The pilot attempted to extend the landing gear using emergency procedures with no success. The pilot then decided to conduct a return to Tindal Airport, NT and contacted the chief pilot and engineer in-flight. After unsuccessfully conducting troubleshooting procedures, it was decided the pilot would have to conduct a wheels up landing at a private airstrip with a grass runway area near Katherine, NT.
While the runway was prepared and emergency services were organised, the pilot entered a holding pattern to burn off fuel. At 1400 Central Standard Time, after multiple practice approaches, a wheels up landing was conducted on the grass strip resulting in a propeller strike and minor damage to the fuselage.
Following the incident, an inspection of the landing gear revealed that the hydraulic line connected to the nose wheel actuator had separated from its fitting. This subsequently resulted in a loss of hydraulic fluid in the gear down hydraulic line.
Unanticipated failures can occur at any given time during flight. In this instance, the pilot took all appropriate actions by following non-normal procedures, communicating and coordinating with ground staff to conduct additional checks to assess the situation, and ensuring that he was well prepared for the wheels up landing resulting in a safe outcome.
This accident not only highlights the importance of comprehensive and periodic maintenance inspections, but also the importance of following emergency checklists and procedures and using every resource available to help resolve an issue.
