Boeing F70207-151 Rigging Pins Kit – 737 MAX Flight Controls

The Boeing F70207-151 Rigging Pins Kit is the Boeing-specified tooling set for flight control rigging on the 737 MAX family of aircraft. The kit contains all of the precision rigging pins required to immobilize rotational components in the flight control system during control surface installation, calibration, and adjustment procedures. Proper rigging ensures that control surfaces are correctly aligned and respond accurately to pilot and autopilot inputs — making this kit essential tooling for any MRO facility or airline maintenance operation supporting the 737 MAX fleet.

Aircraft Applicability

• Boeing 737-8 (737 MAX 8)
• Boeing 737-8200 (737 MAX 8-200)
• Boeing 737-9 (737 MAX 9)
• Boeing 737-10 (737 MAX 10)

Purpose & Function

Flight control rigging is a critical maintenance procedure that ensures ailerons, elevators, rudder, spoilers, and other control surfaces are calibrated to the correct neutral positions, travel limits, and cable tensions specified in the Boeing Aircraft Maintenance Manual (AMM). The F70207-151 rigging pin kit provides the individual pins needed to lock bellcranks, quadrants, and other rotational linkages in their rigged positions during these procedures. Without proper rigging pins, technicians cannot verify or set accurate control surface travel, which directly impacts flight safety.

Key Features

• Complete pin set covering all flight control rigging points on 737 MAX aircraft per Boeing AMM Chapter 27
• Precision-machined pins designed to fit Boeing-specified rigging holes in bellcranks, quadrants, and linkage assemblies
• Immobilizes rotational components to establish accurate control surface neutral positions and travel limits
• Supports aileron, elevator, rudder, spoiler, and trim system rigging procedures
• Required tooling for control cable tension checks and adjustments
• 737 MAX-specific configuration — updated from earlier 737NG and Classic kits to reflect MAX flight control system architecture

Supersession & Related Part Numbers

The Boeing F70207 rigging pin kit family spans the full 737 lineage. The F70207-151 is the current-production kit designated specifically for the 737 MAX series. Operators and MROs transitioning tooling inventories from 737NG to 737 MAX should note that the F70207-109 (737NG) kit does not substitute for the -151 on MAX aircraft. Related part numbers in the F70207 family include:

• F70207-135 – 737 Original / Classic (737-100/200/300/400/500)
• F70207-139 – 737 Classic (alternate)
• F70207-109 – 737NG (737-600/700/800/900)
• F70207-151 – 737 MAX (737-8/9/10/8200) — this kit

Typical Maintenance Applications

• Aileron rigging and travel limit verification
• Elevator rigging and calibration
• Rudder system rigging and centering
• Spoiler and speed brake rigging
• Stabilizer trim system calibration
• Control cable tension measurement and adjustment
• Flight control system restoration after component R&R
• Post heavy-check flight control re-rigging (C-check, D-check)

Why This Tool Matters

Accurate flight control rigging is one of the most safety-critical maintenance procedures performed on any commercial aircraft. Incorrectly rigged controls can result in asymmetric surface deflection, reduced control authority, or autopilot trim anomalies. Boeing requires the use of specific rigging pins — not improvised tooling — to lock flight control linkages during these procedures. The F70207-151 ensures that 737 MAX operators and MRO facilities have the correct, Boeing-approved pin set for every rigging point called out in the AMM, supporting both regulatory compliance and airworthiness.
