Technical Service Bulletin SIL 820 — 2012 ALTEC AT200A

Some customers have reported a crack in the side plate of the mounting frame on some AT200A aerial devices built on Ford F450/F550 chassis from 2011 to 2016 with non-steel utility bodies. Altec requires that each unit be inspected for cracking in the mounting frame side plate no later than the next periodic maintenance interval. Altec requires the kit to be installed within one year of the inspection if the side plate has no cracking or within 90 days of the inspection if the side plate is partially cracked. If the side plate is fully cracked, the unit must be taken out of service until the kit is installed. The inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer’s warranty provider. All welds must be applied by a welder having the AWS D1.1 3G qualification for steel. An Altec Mobile Service technician can perform this inspection but is not able to perform this repair. Altec will perform the repair for free at an Altec facility.
