Duncan Aviation Parts & Rotables Sales has built and maintained one of thelargest business aircraft parts inventory in the industry. Our team of aviation professionals has the experience, contacts and connections to identify and secure some of the hardest to find business aircraft parts.
Because of our long history and experience with the Hawker aircraft, we know the most commonly exchanged parts and keep an inventory available to meet customer needs.
Below are some of the more commonly exchanged life-limited parts on a Hawker 125 airframe that have been known to not make the next Time Before Overhaul (TBO).
Sequence valves are required Overhaul items and have to be overhauled at the required Chapter 5 Interval. However, sometimes they do not make the TBO due to seal failure and contamination of the hydraulic fluid, leading to internal slide and sleeve failure.
Starter generators are exposed to a lot of abuse while operating in a constantly vibrating environment with lots of heat. These conditions over time take their toll, leading to problems, such as not coming on line, unable to be paralleled and premature brush wear.
The Hawker 125 series aircraft utilizes an axle-mounted Maxaret to control skid conditions. It is a required overhaul item and needs to be removed at the necessary intervals. It is not uncommon for valve wear and seal failure to cause leaking, requiring removal before TBO. When removing Maxarets, be sure to use the proper Maxaret extraction tool and procedures to avoid unnecessary damage and expensive overhaul costs.
The aircraft uses this bypass valve to regulate cabin temperature to the desired setting. Due to ever-changing cabin temperatures, this valve is always opening and closing. Failures such as inop, slow to operate and does not modulate result in unwanted cabin temperature ranges.
Just like the sequence valves, the Airbrake Actuator is a hydraulic unit with many seals. These seals have been known to fail before the next required overhaul interval and may cause the unit to be exchanged earlier.
