Owner Advisory

July 20, 2010 SB09-27-01AR3

Dear Cessna Owner:

This Owner Advisory is to inform you that SB09-27-01 Revision 3 Rudder Hinge and Bracket Inspection

has been issued.

The paragraphs that follow give a historical summary of previously issued revisions:

A visual inspection of the lower rudder hinge or bracket and the upper and middle rudder brackets shall be

accomplished for cracking, deformation, or localized discoloration. If any of these conditions are found, the

affected hinge/bracket shall be replaced as stated in this Service Bulletin.

SB09-27-01 Revision 1 provided a new design hinge and brackets for installation when replacements were

required for the previous design parts. The new hinge and brackets are made of different material, incorporate

a machined shoulder for enhanced bearing retention, and include the application of corrosion protection primer

and a top coat of white paint.

SB09-27-01 Revision 2 included a modification kit for replacement of the brackets/hinges, instructions for

rudder travel verification, an allowance for utilizing different length hardware to ensure adequate thread

engagement, and instructions to verify proper hardware thread engagement of previously installed brackets and

hinges. Additionally, Revision 2 is FAA-approved as an Alternative Method of Compliance for AD2009-09-09.

SB09-27-01 Revision 3 adds airplane serial numbers that had the new-design hinge and brackets installed

at the factory. These added airplane serial numbers are required to be inspected to verify rudder travel and

for correct hardware thread engagement. Modification Kit MK400-27-01 has been revised to include two

larger rudder travel stop bushings. Additionally, SB09-27-01 Revision 3 is FAA approved as an Alternative

Method of Compliance for AD2009-09-09.

Non-compliance with SB09-27-01 Revision 3 could allow any of the above described conditions to exist and

if not corrected, may result in failure of more than one hinge or bracket which could potentially result in the

loss of rudder control.

COMPLIANCE REQUIREMENTS

For airplanes that have not accomplished the initial inspection:

Compliance is mandatory: Accomplish the initial inspection as soon as practical, not to exceed 10 flight

hours or 30 days, whichever occurs first.

NOTE: If the airplane must be flown before the initial inspection is accomplished, the pilot in command must

do a check of the rudder hardware for good condition and security, as directed by Area 7 of the

Preflight Inspection Checklist in Section 4 of the Pilot’s Operating Handbook and FAA Approved

Airplane Flight Manual.

If the airplane will be flown after the initial inspection, but before the installation of the new-design rudder

hinge/brackets, the rudder hinge and brackets visual inspections must be performed by maintenance personnel

using the following schedule:

Inspection Interval Required Action

Initial inspection within 10 flight hours or 30 days,

whichever occurs first

Visual 10x magnification inspection with the rudder

removed

Recurring inspection every 25 flight hours or 90 days,

whichever occurs first

Visual inspection with the rudder remaining in place

Recurring inspection every 50 flight hours or 180

days, whichever occurs first

Visual 10x magnification inspection with the rudder

removed

NOTE: Compliance with Service Bulletin SB09-27-01 Revision 2 or Revision 3 equates to full compliance, and

the recurring inspections of this Service Bulletin will no longer be required.

For airplanes that are in compliance with SB09-27-01 Original Issue or SB09-27-01 Revision 1 only:

Compliance is mandatory: SB09-27-01 Revision 3 shall be accomplished as soon as practical within the next

50 flight hours or 6 months, whichever occurs first.

For airplanes that are not in compliance with SB09-27-01 Revision 2

and

Model 350 Airplane serial numbers 42010, 42559, 421014, 421018, and 421020

These airplanes already have the new design rudder hinge and/or brackets installed. (Modification Kit

MK400-27-01A installation is not required.) Specifically the following action shall be accomplished:

• Do an inspection of the hinge/brackets attachment hardware for correct thread engagement and

accomplish the rudder travel check in accordance with Step 2 of the Accomplishment Instructions in this
