Essential Functions:

  • Lead mass properties analyses, weight control activities, and report for major aircraft modifications using computer aided design (CAD) tools, Microsoft Excel, and related engineering systems.
  • Calculate and estimate component weights, moment arms, and mass moments of inertia from engineering drawings, CAD models, vendor data, and aircraft records.
  • Evaluate aircraft weight and balance impacts resulting from multiple concurrent modifications and develop aircraft mass distributions in support of loads development.
  • Establish and maintain weight control plans, target allocations, and status reporting for weight-critical programs.
  • Prepare aircraft weight charts, inventories, and engineering reports that document analytical results and actual aircraft weighing.
  • Lead mass properties tasks across several contracts and coordinate with design, structural, loads, manufacturing, flight test, and certification stakeholders.
  • Mentor less experienced engineers and provide technical leadership on methods, tools, estimates, and execution planning.
  • Support new business pursuits by developing engineering estimates, reviewing statements of work, and contributing to recurring labor forecasts.
  • Leading complex technical tasks or project initiatives with minimal oversight and providing guidance to other engineers.
  • Working knowledge of Microsoft Excel, Word, and PowerPoint, plus experience using CAD models and engineering drawings to support mass properties analysis.
  • Must be able to travel to and from the flight line and work in aircraft hangar environments, including boarding and exiting aircraft when required.
  • Ability to obtain and maintain a DoD Secret security clearance.
  • Travel up to 5% as required to support aircraft weighing, flight line activity, program reviews, and customer meetings.
  • Other duties as assigned by Supervisor.

Qualifications:

  • Bachelor's Degree with nine (9) years of aircraft mass properties, fixed-wing weight and balance analysis, and weight control for aircraft modification programs experience.
  • Graduate Degree or equivalent with seven (7) years of aircraft mass properties, fixed-wing weight and balance analysis, and weight control for aircraft modification programs experience.
  • In lieu of a degree, minimum of 13 years of aircraft mass properties, fixed-wing weight and balance analysis, and weight control for aircraft modification programs experience.
  • Must be a U.S. Citizen.

Preferred Additional Skills:

  • Experience with Automated Weight and Balance System (AWBS) software or comparable mass properties tools.
  • Understanding of FAA and military weight and balance reporting requirements and airworthiness documentation.
  • Experience with aircraft weighing, inventory, and maintaining certified weight records.
  • Advanced skill in managing large data sets and automating calculations in Microsoft Excel.
