The following AD(s) were released on 3/6/2006:

-----------------------------------------------------

AD NUMBER: 2006-05-05
MANUFACTURER: MT-Propeller Entwicklung GmbH
SUBJECT: Airworthiness Directive 2006-05-05
SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for certain MT-Propeller Entwicklung GmbH variable pitch
and fixed pitch propellers with serial numbers (SNs) below 95000, which
have not been overhauled since April 1994. This AD requires overhauling
the propeller blades of these propellers within 30 days after the
effective date of the AD. This AD also requires performing initial and
repetitive visual inspections of affected propeller blades. This AD also
requires removing all propeller blades from service with damaged erosion
sheath bonding or loose erosion sheaths and installing any missing or
damaged polyurethane protective strips. This AD results from reports of
stainless steel leading edge erosion sheaths separating from propeller
blades and reports of propeller blades with damaged or missing
polyurethane protective strips (PU-protection tape) due to insufficient
inspection procedures in older MT-Propeller Entwicklung GmbH Operation &
Installation Manuals. We are issuing this AD to prevent erosion sheath
separation leading to damage of the airplane.
