Maintenance leaders, TACOM Safety of Use (SOU) message 22-002 advises you to inspect the seat belt assemblies (both lap and shoulder seat belts) in your up-armored HMMWVs.
Quality control personnel identified that connector webbing was improperly sewn onto the metal tongue on some HMMWV models. The improperly sewn belts will still click when used and give the operator the impression they're connected properly; they aren’t.
Be warned that the improperly sewn seat belts will have reduced holding strength and may fail in the event of an accident, which could result in potentially severe or fatal injuries.
Up-Armored HMMWV Models Affected
