Pedron Aircraft Works in Denton, TX is certified by, and utilizes Dynamic Solutions propeller balancing equipment.
-Propeller Balance FAQs:
What is Dynamic Propeller Balancing?
Dynamic Propeller Balancing is a process utilizing computer analysis to balance the entire propulsion system.
Why Should I Balance My Propeller?
Propeller mass unbalance causes undue physical and structural fatigue.
We have all seen evidence of propeller unbalance:
· Cowling and baffle wear and cracks.
· Spinner failures
· Failed exhaust pipes, brackets, and clamps
· Loose rivets and fasteners
· Abnormal engine control cable wear
· Unserviceable crankshafts at overhaul
· Alternator bracket failures
· Premature instrument and avionics failures
· Premature landing light failures
· Abnormal airframe and engine vibration
What are the Vibration Limits?
Hartzell Standard Practices manual calls for Dynamic Balance of .2
inches per second (IPS) or better.
How Is Dynamic Propeller Balancing Accomplished?
Pedron Aircraft Works in Denton, TX, utilizes state of the art
digital balancing equipment consisting of a Balance Computer, an accelerometer
to detect vibration amplitude,
Sensor attachment is non invasive. After equipment is attached,
3-5 balance runs are accomplished.
Once analysis is accomplished, small amounts of trim weight are attached at prescribed phase angles in accordance with approved procedures and in amounts to compensate for mass imbalance.
When Should I Balance My Propeller/s?
· Propeller Balancing should be accomplished every 500 hours-time in
service or after any maintenance requiring major propeller blending.
Propeller balancing should be accomplished after propeller or major engine component removal or replacement, including engine or prop overhaul.
and passengers WILL notice the difference. Decreased vibration means decreased
physical and structural fatigue.
As the owners and operators you can expect decreased maintenance costs related to vibration induced wear and failures.
