Nose Landing Gear - Piper SENECA II Service Manual

7-9. NOSE LANDING GEAR

7-9A. MODIFIED COMPONENTS.
The following parts have been modified to increase their service life:
NOTE: Immediate replacement of the currently installed part is not required, as long as the part meets
inspection and time-in-service requirements. When replacement is required, use the parts
identified below.
a. Drag link-to-nose gear strut bolt, P/N 400-274 (AN7-35).
The Nose Gear Installation has been revised to change this AN7-35 bolt to the P/N 693-215,
(NAS6207-50D) bolt that is stronger. This bolt change is approved for all PA-34 Series aircraft, and
is an Alternate Method of Compliance as a substitute for the P/N 400-274 (AN7-35) bolt per AD
2005-13-16.
b. Steering Channel Assembly 95394-000.
The Steering Channel has been revised to increase the material thickness by 25% and the height
increased to prevent "ball-out-of-track" failures. The part number for the redesigned Steering
Channel is 95394-005. The 95394-005 Steering Channel is approved for all PA-34 Series aircraft.
c. Actuator Mount Bracket P/N 95724 and Bushing P/N 95061-89.
The Actuator Mount Bracket has gone through two major design changes, from aluminum (never
installed in these airplanes) to steel, and a recent change adding reinforcements to increase the
bearing surfaces for the P/N 95061-089 bushing.
In S/N's 34-7570001 through 34-7570050 (with aluminum bracket), visually inspect the aluminum
mount bracket for wear, cracks, loose rivets and other damage, within the next 50 hours and at 50
hour intervals thereafter. For all aircraft in this serial number range that have had the steel mount
bracket installed (95724-004 thru -007, as applicable), inspection requirements shall be within the
next 50 hours and at 100 hour intervals thereafter.
In S/N's 34-7570051 through 34-8170092 (with steel bracket), visually inspect the steel mount
bracket for wear, cracks, loose rivets and elongation of the attachment hole for the P/N 95061-089
bushing, within the next 50 hours and at 100 hour intervals thereafter.
Procure and install Piper Kit No. 767-358, if the aluminum or steel Actuator Mount Bracket are
discrepant and must be replaced. This kit includes the latest design actuator mount bracket (i. e. -
P/N 95724-005) and new, required, hardware for attaching the Nose Gear Retraction Link
Assembly P/N 95712-04.
d. Turn Limit Indicator
Piper Kit No. 767-368 provides a Turn Limit Indicator for installation on these airplanes. The Turn
Limit Indicator is being added to help reduce the incidence of turn stop boss failure (on the upper
strut tube assembly P/N 95720).
