Qualifications
• B.S. in Aerospace Engineering and over 23 years hands-on experience in weight and
balance, mass properties, etc in aerospace;
• Excellent working knowledge of CatiaV5 using VPM, ENOVIA (LCA) , in terms of mass
properties analysis and inertia data analysis and collection and working knowledge of
Unigraphics (NX)/Teamcenter operations.
• Good working knowledge of Weights and Balance Manual writing, reporting and
updating, supporting airworthiness and certification personnel.

Experience
2015 – Present GENERAL DYNAMICS LAND SYSTEMS (Advantage Res.), Sterling Heights, MI.
Contract Engineering Specialist – Mass Properties (Weights) Grp. / Stryker LAV
• Used Teamcenter/Unigraphics (NX) op-systems to extract mass property engineering info
to perform vehicle systems & structure weight and balance calculations;
• Exported Unigraphics BOM data into worksheets (Excel) to format data and check data for
errors and conformity. Then, input CG & MOI data into Mass Property Tool (MPT)
database for various Stryker vehicle variants.
• Performed weight validation (weighing detail parts; bare hulls; full-up variants) for Stryker
family of vehicles.
• Inform other Stryker group personnel about Teamcenter BOM changes that had impact on
weight & balance in MPT database;
2010 – 2015 BOMBARDIER – LEARJET, Wichita, KS.
Engineering Specialist – Mass Properties (Weights) Grp. / L85 Business Jet
• Used systems such as electronic routing database (ERD & EDIMS), Integrated Change
Management System (ICMS), E-Room, Product Change Requests (PCR) & ENOVIA op-
system to obtain engineering info to perform systems (avionics/electrical) and interiors
structure weight and balance calculations;
• Extract mass property data from Catia V5 solid models for use in trade study calculation
sheets, weight status reports, and PCR weight impact statements.
• Track supplier weight status reports for errors and format conformity;
• Update other L85 group leaders about design changes that had major impact on weight &
balance;
• Suggested design changes that have impact on weight and balance requirements;

Sr. Engineer – Mass Properties (Weights) Grp. / CX, XLS, CJ)
• Created mass property data using Catia solid modelling functions;
• Used PIOS-based system & SAP interface to obtain parts lists, ECRs, and other engineering
info to perform weight and balance calculations;
• Collaborated with delivery systems in order to support air worthiness & type certification
(weight & balance manual);
• Reviewed engineering drawings (structures & systems, including avionics & electrical) for
mass property changes to evaluate impact on weight & CG;
• Estimated and physically weighed individual parts & assemblies to help maintain accuracy
of master databases;
• Performed quarterly checkout runs of group calculation sheets that include updated mass
property data;
• Compiled quarterly weight & balance reports;
• Participated actively in weekly engineering coordination meetings;
• Supported internal and external customers by working marketing studies, sample loadings,
and equipment listing;
• Updated other group leaders about design changes that had major impact on weight &
balance;
• Suggested design changes that have minimal impact on weights and balance requirements;
• Reviewed and advised on major internal customers requests, such as:
