NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Equipment Query EQ10-009.

On June 22, 2010, Trans/Air Manufacturing (Trans/Air) reported that it had decided certain TA73 evaporators, manufactured between August 2, 1999, and May 15, 2007, contain a safety related defect.

Trans/Air reported that these evaporators contain a power resistor to regulate blower speed.

Should a short occur in the low or medium speed circuit while the blower is in high speed, the short may cause the resistor to melt and possibly ignite the plastic blower housing to which it is mounted.

A melted blower housing could result in a fire.

This issue was assigned recall number 10E-028.

On December 8, 2010, the Recall Management Division (RMD) mailed Information Request (IR) letters to 7 vehicle manufacturers on Trans/Air's customer list.

All 7 manufacturers responded to RMD's IR letter.

Glaval Bus had filed their subsequent Defect Report before receiving RMD's IR letter and it was given recall number 10V-618.

It was discovered that Coachmen RV's bus assets were purchased by a company called All American Group.

After research with Trans/Air, All American Group discovered that no past Coachmen units were affected and they were accidentally included on Trans/Air's customer list.

Trolley Enterprises responded that they had gone out of business in July 2010.

Previous employees are presently searching for any remaining customer records and will forward them to RMD if recovered.

The following Defect Reports were received as a result of this EQ:10V-637 - Micro Bird School Buses 10V-645 - Micro Bird Transit Buses 10V-641 - Elkhart Coach 10V-652 - Coach & Equipment Manufacturing Corp. 11V-091 - Double K. Inc.

This EQ is closed.

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
