alleviated within 90 days, a letter must be submitted to the aircraft controlling custodian (ACC), through the chain of command, advising of the personnel problems, action taken, and intent to continue the assignments. ACCs will take action to authorize activities to continue or to curtail the assignment. The letter will contain name, rate, Navy enlisted classification (NEC), and functional area. Permanent CDQARs may be assigned to organizational maintenance activities that have minimal ordnance delivery in their assigned mission, and where manning the armament billet would not be justified. An organizational activity may also designate a permanent aircrew personal protective/survival equipment CDQAR and an egress/environmental systems CDQAR when the activity’s aircraft are not equipped with ejection seats. Permanent CDQARs also may be designated to supplement multiple work shifts or detachments, provided QA division billets are fully manned. Permanent CDQARs may also be assigned when the activity maintains four or less aircraft and is organized according to guidelines set forth in the NAMP. COLLATERAL DUTY INSPECTORS The CDIs assigned to the production or maintenance training unit (MTU) work centers inspect all work and comply with the required QA inspections during all maintenance actions performed by their respective work centers. They are responsible to the QA officer when performing these functions. CDIs spot check all work in progress. This requires them to be familiar with the provisions and responsibilities of the programs that QA manages and monitors. The QA division establishes minimum qualifications for personnel selected for CDI. Division officers are responsible for ensuring that sufficient qualified personnel are nominated for CDI to comply with QA inspections required during all maintenance actions. Due to the importance and responsibility of duties performed by CDIs, division officers and work center supervisors must carefully screen all candidates for these assignments. CDIs must demonstrate their knowledge and experience on the particular type of equipment by successfully passing a locally prepared written test administered by the QA division. In addition, a locally prepared oral or practical examination may be administered. When a CDI is transferred from a production work center, his or her designation as a CDI for that work center remains valid for only as long as his or her qualifications are current, as judged by the cognizant division officer. NOTE: A CDI will NOT inspect his or her own work and sign as inspector. QUALITY ASSURANCE REPRESENTATIVE TRAINING The QA officer ensures that personnel assigned to perform QA functions receive continuous training in inspecting, testing, and quality control methods specifically applicable to their area of assignment. The QA officer also ensures that QARs receive cross training to perform those QA functions not in their assigned area. This training should include local training courses, on-the-job training (OJT), rotation of assignments, personnel qualifications standards (PQS), and formal schools. According to OPNAVINST 4790.2, QARs should attend a Fleet Aviation Specialized Operational Training Group Detachment QA course. Division officers are responsible for establishing and maintaining training programs for production personnel involved with QA functions. This responsibility includes training in troubleshooting, testing, and inspection techniques; ensuring that operations requiring certified operators are accomplished; and that steps are taken to qualify and certify affected personnel. QARs, CDQARs, and CDIs must be designated in writing by the AMO. The only deviation authorized allows the officer in charge (OIC) of a detachment to designate QA personnel provided (1) the deployment period is more than 90 days, and (2) all procedures and requirements for designating QA personnel are accomplished by the detachment. See figure 6-1 for a sample of a Quality Assurance Representative/ Inspector Recommendation/Designation form. ISSUE AND CONTROL OF QUALITY ASSURANCE STAMPS QA stamps may be used in place of a signature. They are required in an intermediate maintenance activity/aircraft intermediate maintenance department (IMA/AIMD), but are optional at organizational-level maintenance. In an IMA/AIMD, all QARs, CDQARs, and CDIs receive QA stamps. At the organizational level, QA stamps are to be used by QARs and CDQARs only. These open-purchased, numbered, impression stamps, which 6-11
