In any high-value aircraft sales transaction, immediate access to high-quality market intelligence is key to optimizing returns and achieving a successful result.
If your aircraft will be sitting idle for longer than normal, we recommend you take extra steps to keep your engines in working condition and minimize the potential for deterioration. Engine preservation is critical during times of long-term storage, with some unfortunate effects when procedures are not followed.
Hydrostatic testing is often required at certain intervals for Aircraft Oxygen Cylinders, Fire Extinguishers and Pneumatic Bottles. The interval at which these are due and what is to be done is sometimes confusing. It’s not only important to know when these are due but also what is to be done.
It is crucial to follow recommended best practices during aircraft tire storage to prevent tire distortion.
Duncan Aviation’s flight operations have a list of things done regularly that could be considered preventative maintenance. Most of the items are service-related, but many AOG situations are prevented by doing them.
The normal engine startup sequence removes power from the avionics system, causing it to drop offline. SB560XL-24-14R2 prevents this occurrence.
The compressor bleed control system on the PW500 series engines provides surge-free operation throughout the entire engine operating range.
It has been several years since we’ve observed saddle tank corrosion aboard the CL604; however, we are beginning to see it more often in the field.
The temperature control system on the Cessna 525 can be rather difficult to troubleshoot considering the many components involved.
When a radar unit is in for repair, having it tested in an environmental/altitude chamber assists in duplicating ‘no fault founds’ and finding intermittent squawks.
According to Service Letter (SL) No. 2843 and 2844, Universal Avionics has announced they will cease repair, support and the navigation database updates for the UNS-1M and UNS-1Msp series Navigation Management System, effective January 1, 2013.
Duncan Aviation has recently observed an aging aircraft issue in regards to the Aux Cabin Heat in 20 & 30 Series Learjets not equipped with a Meggitt freon system.
During autopilot-engaged flight, oscillations can occur in the roll, pitch or yaw axis. The most commonly squawked oscillation occurs in pitch and is often referred to as porpoising.
Learjet is planning on releasing a Temporary Revision (TR) to Chapter 5 on November 29, 2010, that will reduce the life limit of the end cap.
Operators of Hawker 750, 800XPC, 850XP and 900XP aircraft may be unaware of new storage requirements introduced.
