AGENCY: Federal Aviation
Administration (FAA), Department of
ACTION: Final rule.
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
the Dowty Propellers, propeller models
listed above. That AD currently
requires, for all Dowty Rotol propellers,
visual inspections for seizure and for
cadmium plating of the blade pitch
change operating links and eyebolt fork
assemblies. That AD also requires
replacement or heat-treatment of the
blade pitch change operating links and
eyebolt fork assemblies, if necessary.
This AD requires the same actions, but
only for certain propeller models. This
AD results from the FAA determining
that AD 70-16-02 does not apply to all
propellers, since current Dowty
propellers are differently designed. We
are issuing this AD supersedure to
specify the affected propeller models,
and to prevent seizure or embrittlement
and cracking of the blade pitch change
operating links and eyebolt fork
assemblies, which could result in
reduced controllability of the airplane.
DATES: This AD becomes effective June
25, 2010. The Director of the Federal
Register approved the incorporation by
reference of certain publications listed
in the regulations as of June 25, 2010.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR part 39 by
superseding AD 70-16-02, Amendment
39-1503 (37 FR 16535, August 16,
1972), with a proposed AD. The
proposed AD applies to certain Dowty
Propellers, propeller models. We
published the proposed AD in the
Federal Register on August 29, 2008 (74
FR 50892). That action proposed to
require visual inspections before further
flight of the blade pitch change
operating links and eyebolt fork
assemblies and replacement or heat-
treatment of them, if necessary, for
certain Dowty Propellers, propeller

Request To Revise the Proposed
One commenter, a private citizen,
states that there were no Dowty Rotol
propellers installed on Convair 240,
340, and 440 airplanes. However, the
commenter also states that Convair 240,
340, and 440 airplanes modified by
supplemental type certificates (STC)
SA1054WE and SA1096SW, do have
Dowty Rotol propellers installed. The
propeller R.245/4-40-4.5 is used on a
Convair model 240, redesignated as
Convair model 600 on supplemental
type certificate (STC) SA1054WE, and
the propellers R.245/4-40-4.5 and
Here’s what’s next.
