currently have a matter where a gent did not comply with a prop AD for
years and it eventually failed in flight.
Mark, Hamid and Jeff,
Go to:
For ADs, Enter your prop designation. If the following shows
up,
|
AD 2006-18-15 This AD requires initial and
repetitive eddy current inspections (ECI) of the front cylinder half of
the propeller hub for cracks and removing cracked hubs from service before
further flight. In addition, this AD allows installation of an improved
design propeller hub (suffix SN ''A'' or ''B'') as terminating action to
the repetitive ECI. This AD results from a report of a propeller blade
separating from a propeller hub. We are issuing this AD to prevent failure
of the propeller hub causing blade separation and subsequent loss of
airplane control.

1. Look at your propeller log book.
2. Check the hub Serial No.
3. If it ends in A or B, ignore the ECI warning.
4. If not, take off your shiny spinner and look for the serial number on
the hub. If it ends in A or B, find out why your log book doesn't match
the hub. Also, ignore the ECI warning with prejudice.
5. If #3 and #4 don't apply, get a copy of the AD and any
referenced Hartzell SB. Act on it.
6. Even if you don't think you need it, apply Aeroshell #6 greasy
grease as outlined in your Hartzell prop log/service handbook.
If Hartzell knows you have one of their props, they are very good at
sending you updates for the appropriate prop manual and any new
service information. If they don't know about you and your Hartzell prop,
contact them... I am sure their lawyers will be happy to send you the
correct prop manual.

Information is power (literally).
PS: This calming information is free and worth every penny paid. Your
experimental airplane is risky and, when flown by yourself, it is even more
risky. Each person must assume the risk for his/her own actions or
inactions. In other words, no one is to blame but yourself and any
inherent Type-A personality imperfections that are assigned to you by your
psychiatrist are your's alone. If any, deal with them - the stick is in
your hand.
