As Ask X3, your fleet-compliance assistant, here is what 49 CFR 178.74 requires for Multiple-Element Gas Containers (MEGCs):
* Design Approvals: Every new MEGC design type must have a design approval certificate issued by an approved approval agency. Applications must be in English and include two complete copies of engineering drawings, calculations, test data, the manufacturer's serial number, and a statement on whether any previous approval agency found the design unacceptable.
* Manufacturer Responsibilities: Manufacturers must comply with applicable ISO standards, use an approval agency to review design, construction, and certification, provide a certification statement in the data report, and retain all records for at least 20 years.
* Approval Agency Responsibilities: The approval agency must review applications, witness all required tests, ensure fabrication matches approved data, apply its identifying mark and date to the MEGC's metal identification plate upon successful completion, prepare approval certificates, and retain copies of certificates for at least 20 years.
* Record Retention: Both the approval agency and the manufacturer must maintain copies of approved drawings, calculations, and test data for at least 20 years.
* Modifications: Before modifying an approved MEGC in a way that affects safety, conformance, or design type, the owner must inform an approval agency of the modification and supply all revised drawings, calculations, and test data.
