About this file
This is a procurement justification document for the G689 CherryLock Riveter with attachments, a specialized pneumatic power tool required for aircraft structural repairs.
The procurement is justified by the operational requirement to install CherryLock NAS1400 blind rivets larger than -9 grip length, which current tooling lacks the capacity to perform. Without this equipment, critical structural repairs cannot be completed, resulting in extended aircraft downtime and degraded mission readiness at home station and deployed locations. The riveter gun must meet specific technical specifications including air pressure operation between 90-110 PSI, a 1.475-inch stroke, pulling force of 3,800 lbs at 90 PSI, weight of 12.85 lbs, noise level of 74.1 dB(A), vibration less than 2.5 m/s², and air consumption of 0.50 SCF per cycle. The equipment must be capable of installing blind rivets NAS1398, NAS1399, NAS1400, NAS1738, and NAS1739 with -8 rivet diameter and all grip lengths. Additionally, the riveter must accommodate the 680B46 adapter for H9055 pulling heads in sizes 3/32, 1/8, 5/32, and 3/16 inch to install CherryLOCK "A" and MS rivets of all grip lengths, and must be compatible with H681-3C, H681-4C, H681-5C, H681-6C, and H681-8C pulling head assemblies.

G689 CherryLock Riveter w/attachments
Justification for Procurement
Our current tooling lacks the pull strength to install CherryLock NAS1400 blind rivets larger than a -9 grip length. These fasteners require a specialized power unit capable of installing these larger fasteners.
This equipment is an operational requirement, without this tooling it halts critical structural repairs.
This directly results in extended aircraft downtime while sourcing equipment from other installations and also degrades overall mission readiness home station and deployed.
Salient of Characteristics
Riveter gun must meet the following specifications:
Air Pressure operation range 90 to 110 PSI(6,2 bar to 7,6 bar) MAX
STROKE 1.475 inch (37,47mm)
PULLING FORCE 3,800 lbs. (16,9 kN) @ 90 PSI (6,2 bar)
WEIGHT 12.85 lbs. (5,90 kg)
NOISE LEVEL 74.1 dB (A)
VIBRATION less than 2.5 m/s2
AIR CONSUMPTION .50 SCF/cycle (14.2 L/cycle)
Capable of installing blind NAS1398, NAS 1399, NAS1400, NAS1738 & NAS 1739 rivets with -8 rivet diameter and all grip lengths.
Must be able to attach 680B46 adapter to install H9055 pulling heads
Must be compatible with 3/32, 1/8, 5/32, 3/16 H9055 pulling heads to install CherryLOCK “A”, MS rivets of all grip lengths.
Must be compatible with H681-3C, H681-4C, H681-5C, H681-6C, H681-8C pulling head assemblies.
