A. Title, Series, and Grade: Aircraft Ordnance Systems Mechanic, WG- 6652-10.

B. References:

1. USOPM Federal Wage System Job Grading Standard for Aircraft Ordnance Systems Mechanic, WG-6652, Aug 74.
2. USOPM Federal Wage System Job Grading Standard for Materials Expediter, WG-6910, Jun 73.

C. Background: This position description was developed due to changes in duties and responsibilities within the Weapons Element. This position has the opportunity to assist the Flight Line Aircraft Ordnance Systems Mechanics which will enable them to learn flight line maintenance.

D. Pay Plan, Series, Title and Grade Determination:

1. Pay Plan: This position (Aircraft Ordnance Systems Mechanic) is determined to be Wage Grade (WG) as their primary duty involves the performance of physical work that requires knowledge or experience of a trade or craft.

2. Series: This is a mixed job involving both Aircraft Ordnance Systems Mechanic (WG-6652) and weapons expediting (WG-6910, Materials Expediter) work assisting journey workers, at the WG-11 in performing simpler and more routine duties of the electronic work. WG-6652 work is predominating. Such work involves the maintenance, repair, assembly, and handling of ordnance systems such as missiles, munitions, armament, associated test equipment, etc. Secondary duties involve the expeditious movement of weapon items into and out of the shop and scheduling of aircraft ordnance requirements to meet daily flying schedules. The position also assists higher level journeyman as required. The assisting duties are based on a “need to” requirement in repairing and maintaining of associated electronic equipment. The assisting work does not require additional electronic skill or knowledge as the higher level journeyman is determining the level of maintenance required. The intent of the assisting duties is for individual development purposes and training of the current incumbents to assume the higher level duties as they become available. This position is therefore titled Aircraft Ordnance Systems Mechanic, WG-6652.

3. Title: Jobs covered by the WG-6652 standard are titled Aircraft Ordnance Systems Mechanic at the WG-10 level and above.

4. Grade: Since this is a mixed series position, references B1 and B2, were used to determine the grade. The four factors used in grading positions in the WG-6910 and WG-6652 series are Skill and Knowledge, Responsibility, Physical Effort and Working Conditions.

a. Skill and Knowledge: This position involves maintaining, repairing and conducting tests using special test equipment and precision measuring devices. Analyzes and isolates system component malfunctions using electronic, pneumatic and electrical test equipment and interpreting wiring diagrams and evaluates and analyzes technical documents and equipment specifications. This skill and knowledge work meets the WG-10 level of the standard which involves a variety of troubleshooting, repairing, defect isolation, related to more complex ordnance equipment usually composed of mechanical, pneumatic, interrelated electrical and hydraulic assemblies and components. It also requires the use of various precision measurement instruments and application and interpretation of wiring diagrams, blueprints, equipment specifications, etc. The incumbent also provides assistance to the higher graded employee in work involving electronic troubleshooting, repairing and maintaining of associated electronic (WG-2604) equipment. The intent of the assisting work is for individual development purposes and training of the current incumbents to assume the higher level duties as they become available. This position also requires skill and knowledge of Weapons Expediting, which involve the routing of weapon items into and out of the shop. These duties equate no higher than WG-07 level in the WG-07 level in the Materials Expediter Standard, WG-6910. This position fully meets the WG-10 of the 6652 standard.

b. Responsibility: Work is performed under the general supervision of the section supervisor. Assignments are given by work orders, inspection reports or verbally. Plans work sequence and carries out assignments. Completed work is spot checked to ensure compliance with accepted trade practices, inspection reviews, etc. This meets the WG-10 level in the standard which involves the supervisor assigning work in the form of oral or written instructions and the mechanic using independent judgment as to the sequence of work, tools to use, etc.

5. Physical Effort: Mechanics at the grade 10 are required to stand, bend stoop, climb, stretch, and work in tiring and uncomfortable positions and in hard to reach places. They frequently lift parts and equipment weighing up to 40 pounds and occasionally up to 75 pounds. This fully meets the requirements for the WG-10.

6. Working Conditions: Mechanics at the grade 10 perform the work either inside or outside, and are subject to prevailing weather conditions, noise, slippery or uneven surfaces, and working in confined areas. They are exposed to the possibility of cuts, burns, grease, oil, dirt, electrical shock, and possible injury when de-arming and arming the system. This fully meets the requirements for the WG-10.

E. Conclusion: Aircraft Ordnance Systems Mechanic, WG-6652-10.
