Another reported problem by Beaver owners has been with the airfilter coming off
the carburetor in flight and striking the prop. This has resulted in several fatalities!
To help prevent this, it is suggested that a small hole be drilled in the back of the
carb and front of the airfilter and that these holes be used to safety wire the
airfilter to the carburetor.
Another update has the two separate vent holes found on the sides of the carbs
being replaced by one line with vent holes in the bottom. This prevents improper
fuel to air mixture in the carburetor.
Owners have also reported their throttle cables slipping in the retaining clamp at
the throttle handle junction. In Canada many owners have reported their throttle
cables freezing during winter operations.
Some owners have changed the position of their ignition switches after they have
applied full power, or brought power back, hitting their ignition switch and
shutting their engines off.
Propeller damage The Beaver family of aircraft are pushes, this means that the
propeller is found at the rear of the aircraft, thus anything that exist from the
aircraft in flight usually finds its way into the propeller
Items that have been reported
entering the prop are parts of the
exhaust springs and upper and lower
engine cowl screws/washers.
It is suggested that all of the
exhaust springs be SAFETY WIRED
AND THEN FILLED WITH SILICONE.
This will hold the spring together if it fails. Silicone applied to the head of the cowl screws will prevent them from going into the
prop as well.
If your engine is equipped with an aluminum engine cowls these crack around the exhaust and intake manifolds. The fix the
problem replace them with a STEEL COWL. To date I have no reports of the steel
cowl failing.
Another reported item that has entered the prop is the screws and washers holding
the upper and lower cowls together. A dab of silicone over the washer and screws
will prevent this from happening.
Several owners have reported their recoil handles entering the propeller. This
happens when the recoil spring looses its strength. A sign of lost strength is when
the pilot has to tug on the handle several times to get the recoil rope to rewind into
the recoil.
Another area of concern on two place Beavers was the recoil rope guide pulleys. When these fail they cut the recoil rope and it
recoils back into the housing, this of course means the owner now has to prop start the engine!
