Safety Recommendation History
From: NTSB
To: SAE International
Date: 6/28/2002
Response: NHTSA's lack of action on companion Safety Recommendation H-97-38 precludes the SAE from developing specifications and requirements for the installation, in heavy trucks with a dual air brake system, of separate low-air-pressure warning devices. Therefore, Safety Recommendation H-97-39 is classified "Closed--No Longer Applicable."

Response: Letter Mail Controlled 03/07/2002 2:58:06 PM MC# 2020260 I do not believe this NTSB Recommendation can be addressed by the SAE Truck and Bus Wheel Subcommittee or through TMC. These type of vehicle specifications are usually handled through the Federal Motor Carrier Safety Administration. In summary, a host of TMC Recommended Practices have been completed since the original NHTSA Special Investigation Report was released in 1992. These Recommended Practices are available as a complete set in The TMC Recommended Practices Manual, or by calling TMC and ordering individual copies of Recommended Practices. TMC also offers many of these Recommended Practices in CD-ROM format, wall chart format, and even pocket reference guide format. I strongly feel the wheel end industry has "raised the bar" concerning wheel end maintenance practices since 1992 and today we continue to develop new Recommended Practices concerning wheel end maintenance and strive to improve the safety of commercial highway vehicles. If you have any questions concerning this information, please feel free to contact me at 937-743-8125, extension 602.
