Promoting the safe enjoyment of aviation for pilots, aircraft builders and enthusiasts.
Mike Busch's article in AOPA Pilot Magazine discusses the reliability of differential compression tests during annual inspections. He highlights inconsistencies in test results, suggesting caution before making decisions based solely on them. Personal experiences with a Cessna 195 illustrate these variations, emphasizing the need for context and further investigation in maintenance practices.
On May 13, 2023, The Bomber Command Museum in Nanton, Alberta, celebrated the 80th anniversary of the Dambusters' missions. The event featured engine demonstrations, a presentation by Richard de Boer on the history of 617 Squadron, and replicas of famous bombs. Future discussions will expand on the significance of the Halifax aircraft in Canadian history.
The author recounts a flight experience where they encountered an engine issue, suspected exhaust problems, and detected exhaust fumes via a carbon monoxide detector. After landing at Ben's airfield, they discovered a crack in the exhaust pipe, which was repaired. Additional information includes newly approved STC for 120 VAC availability on aircraft at fly-ins.
The author experienced high oil temperatures in their Cavalier aircraft after engine installation, initially measuring 205-220 degrees F. They replaced the oil cooler and constructed a shroud to improve airflow, reducing temperatures to 170-195 degrees F. Following an investigation, they confirmed the installation of a necessary Vernatherm, enhancing engine cooling performance.
The author experienced increased oil consumption in their Lycoming O-290D engine due to several issues, including a lack of an oil-air separator and a worn valve guide. Opting for a more reliable solution, they decided to replace the O-290 with a Lycoming O-320-A2B engine, which offers better parts availability and power.
In November 2000, I purchased a partially completed Kitfox Classic IV project. After six years of modifications, my first flight ended in an engine failure, leading to a crash. Through extensive repairs and engine upgrades to a VW engine, I addressed multiple issues such as fuel starvation, overheating, and valve problems, ultimately achieving successful flights.
The article discusses replacing O-rings in Zenair CH250 aircraft brake cylinders to eliminate oil leaks. It explains differences between aircraft and car brakes, outlines necessary repairs, and details the replacement process, including parts sourcing and bleeding techniques. The author emphasizes the importance of cleanliness and the specific tools required for the job.
This summer has been challenging for flying, with a four-week hiatus due to poor weather despite usually logging 30-40 hours. Notably, I attended a fly-in breakfast for the newly opened Linden airstrip. I faced some engine temperature anomalies during a flight to Medicine Hat, but resolved them swiftly. Another flight nearly involved a collision with a deer on the runway.
The author recently began working at Klarenbach Aviation, a small aircraft maintenance company, and has enjoyed diverse tasks on various aircraft. They stress the importance of thorough inspections and share tips for performing annual checks, emphasizing a comfortable work environment and proper technique to prevent mistakes and ensure safety during maintenance.
The author reflects on making modifications to the Buttercup aircraft following the acquisition of a Tailwind design. The introduction of a powerful O-320 engine promises enhanced performance, speed, and climb rates. Suggested changes include expanding fuel capacity and omitting leading edge flaps to increase structural stability and flight capabilities, aiming for greater efficiency and speed.
