Honeywell issued Service Bulletin AS907-72-9094 that calls for the replacement of the #4 carbon seal on the HTF7000/AS907 series engines. We can do this as an engine-only event in as little as 4 days.
Are your aircraft's RVSM operations fully compliant? While FAA requirements shifted away from standalone approved programs, configuration control and height-monitoring standards remain strictly enforced. Learn the key differences between Section 9 and Section 3 pathways and Duncan Aviation’s role in keeping you airworthy.
As business travel demands grow, many owners of piston twins begin looking at turboprops for greater range, payload, reliability, and operational flexibility. But moving to turbine power involves more than buying a larger aircraft. From maintenance planning and pilot training to operating costs and regulatory requirements, a successful transition depends on carefully matching the aircraft to the mission. This article examines the key benefits, tradeoffs, and considerations to help buyers determine whether a turboprop is the right next step for their operation.
Most overhaul delays don't start in the shop. They start with the logbooks when the serial number stamped on a part doesn't match the one listed in the maintenance logs. Reconstructing that paper trail can ground an aircraft for weeks and force you to replace parts that are actually totally fine. Here's a quick breakdown of where Chapter 5 records often fall through the cracks and how to resolve discrepancies before your aircraft goes down.
While the FAA encourages the TCAS 7.1 upgrade, strict ICAO and EASA mandates make it a necessity for international operators. Learn how Version 7.1 improves flight safety, impacts your flight plans, and what certification path your aircraft requires.
Grease alone is the number one defense against corrosion. Corrosion cannot be prevented, but the effects of it can be lessened and controlled if you are aggressive with your grease gun. The greasier the better.
Time sometimes slips by faster than we realize. And while it does, components that are sitting on shelves as serviceable are aging.
Batteries deserve more credit in the successful operation of your aircraft. They are the first component to engage an aircraft’s electrical system and the last line of defense before everything shuts down in an emergency.
Simply put, fuel starvation occurs when the available fuel is unable to reach the engines. Water, debris and microbes in aircraft fuel tanks clog fuel supply lines and filters and ultimately starve the engines of the necessary fuel.
To our neighbors and friends to the north, thank you for being faithful subscribers. We could use your help.
Duncan Aviation technicians have been finding brightened surfaces on both leading edges and engine inlets with dulled finishes and varying degrees of corrosion. Catching it early is the key.
At Duncan Aviation, we encourage you to stay up-to-date on the available Service Bulletins as symbol generator upgrades and improvements become available.
Corrosion doesn’t care what make/model aircraft you have or how many flight hours it sees. All it cares about is getting its start and hoping you are not paying attention.
There are many advantages that carbon disc brakes have over the traditional steel. Keep reading to learn what you can do to increase performance and the life of your carbon disk brakes.
Operators are protected from unexpected engine maintenance costs and extended downtimes with Honeywell's new MSP for their HTF series engines.
