CAA queries emergency
An investigation into the emergency landing of a Sounds Air plane at Marlborough Airport, in Blenheim, is not expected to be finished before the end of March.
A Civil Aviation Authority spokesman said it was seeking further details from Sounds Air "in light of some additional information the CAA has now received" about the nature of the event.
The Cessna Caravan made the emergency landing on December 18 after a loud bang was heard in the cockpit about 10 minutes into the flight from Wellington to Koromiko.
After landing, it was discovered a heat shield between the engine exhaust and the cargo pod of the plane had come loose during the flight. The shield fell off as the plane landed.
