Regular Checks and Balances
To avoid these issues, it’s a good idea to have your propellers assessed routinely. Typically, that means approximately every 1,000 hours of flying time. If a propeller is vibrating too much, then you should have it balanced, following the manufacturer’s procedure.
Smaller PW100 engines with four propeller blades may need more frequent propeller balancing than six-bladed propellers on larger PW100 and PW150 engines. Aircraft that operate in harsh environments, such as those that frequently land and take off on unpaved runways, may also need more careful monitoring. Since they kick up stones, this can cause damage to propeller blades.
The bottom line? When performing PW100 propeller balancing properly to reduce vibration on a regular basis, engine durability increases, maintenance costs drop and a more comfortable passenger experience is assured. New technology developed by P&WC is set to make propeller assessment easier than ever. Read all about this new solution, already available for P&WC-powered ATR and Bombardier Q400 aircraft.
