Cessna aircraft: a safe touchdown
As president of the local flying club, aeroplanes are close to Senior Design Engineer Warwick Sims heart. So, when confronted with an issue on the clubs Cessna 1 series his pilot’s hat came off and engineers cap went on.
Cessna 1 and 2 series aircraft may experience problems with their undercarriage over time, as holes become elongated and the permitted movement exceeds tolerance levels. Whilst not immediately catastrophic it certainly means aircraft are grounded until fixed and with a new set of gear costing around $18,000NZD it could put more than a small dent in the wallets of pilots across the country.
To minimise cost and maximise flying time DC Ross have perfected a fix on current landing gear which involves the accurate wire cutting of the damaged hole to a specified size. A precision bushing is then fitted and cut to fit the attachment bolt. The whole repair is certified safe by aircraft service regulations and the renovations can be done for around a quarter of the price of a new set of landing gear.
“It’s a solution to a problem that may affect all Cessna 1 and 2 aircraft at some point and it’s great to offer something that can benefit aircraft owners all over the world”, Warwick says.
