| Subject: | Acceptable prop strike damage? |
Getting straight to the point, is there a "rule of thumb" for how much damage a
propeller can sustain before a shock load engine strip-down is necessary? I suspect
that the decision lies with the engineer making the assessment.
Today a friend was flying his tail wheel RV6 in a strong crosswind on a tarred
runway and while landing he was dumped by a gust while attempting to go around,
perhaps over-rotated when pushing the stick forward and heard a sound like kerbing
a car's wheels, as he described it. He didn't really feel a vibration,
nor did he hear the engine note change. So it was a fleeting "brrrrt" on the tar
and following the go around pattern flown, a later inspection showing no evidence
on the runway surface.
The engine is an IO320 (I think), the propeller is fixed pitch metal and last 3
to 4 inches of the tips are now curled forward through a full 90 degrees. My
instinct is that a shock load engine strip-down isn't necessary in the circumstances,
but what do I know? Very little indeed, apart from a slight recollection
that damage like minor nicks in prop leading edges can be dressed out provided
that they're not along the 1/3 nearest the hub.
I look forward to your replies, thanks.

It was a beautiful morning.
For those with good eyes, you will notice my static port issues. The altimeter
went slightly negative on the TO roll and very annoying oscillations on the ASI
and altimeter.

There is no rule of thumb. He's had a prop strike. Perform the inspection

Does anyone know what grease is used on the Arplast PV50 propeller hub? I've had
a look through the manual but cant find anything.

I had similar issues with fluctuating airspeed and altimeter. I installed the Europa
wing mounted pitot/static and it has been fine ever since. I think the original
fuselage mounted static ports were the issue.
