Aircraft crimp tool selection guide

This guide shows how wiring shops pick the right crimp tool frame and positioner for an aircraft connector contact, and how to keep the tool verified. It uses DMC documentation and FAA AC 43.13-1B.

Start from the contact

• The aircraft wiring documentation names the contact; cross-reference it to an AS22520 tool and positioner ^[1].
• Wire size decides the frame: AF8 for 12–26 AWG ^[2], AFM8 for 20–32 AWG ^[3].

Positioners and turrets

• The AF8 must be fitted with a turret head, positioner or adjustable head before use ^[2].
• Each positioner data plate lists contacts and selector settings ^[3].

Verification and quality

• Gauge tools periodically with the M22520/3-1 Go/No-Go gauge (DMC G125) ^[2].
• Buy through traceable channels; DMC has warned about non-qualified copies ^[4].
• General wiring practices: FAA AC 43.13-1B, Chapter 11 ^[5].
