I was responsible for providing support to our worldwide customers through management of the design, certification, and implementation of aircraft modification and design change projects for all Viking/De Havilland products, including DHC-2 through DHC-6 and CL-215/215T/415/515. In addition to these tasks I was given the opportunity to support and mentor younger engineers in the various areas of design and certification of aeronautical products.A few major projects I was the project manager include:1. Generation of structural, fatigue, fracture mechanics analysis of an anti-flutter modification used on the CL-215/215T/415/515 aircraft - approving an alternate material to solve in service vibration and cracking failure.2. Evaluation, substantiation, testing and certification of a composite fiberglass epoxy used on the DHC-3 aircraft considering material strength/layups, glass transition temperature and flammability based on the part location.Typical tasks involve:1. Perform detailed 3D designs; generate CAD drawings and related documents, and supportmanufacturing and assembly of components (ASME Y14.100 standards).2. Aircraft structural analysis, including hand calculation experience for mechanical joints. Using resources such as MMPDS, Bruhn, Roark, aircraft fasteners, materials, sheet metal assemblies, machinedfittings.3. Generation of certification compliance plans, engineering design data, substantiation/test reports, operator installation instructions, etc. Provide engineering support for De Havilland owned type designs.4. Correction and revision to existing engineering data packages including IPC, AFM, MMS, among others.5. Evaluation of part and material obsolescence and generating appropriate solutions based on procurable supply and material/strength requirements.6. Interpretation of airworthiness regulations and aerospace standards collaborating with colleagues and providing guidance to interns.

My engineering duties at Canadian North are vast and numerous where was a project lead or worked in a small team. I completed tasks in aircraft repair, part design, part installation, certification and testing. These tasks involve interdependent mechanical/electrical kinematic systems while working in a small team of engineers.A few major projects I have participated as either team member or team lead are:1. Major modification to an ATR42-500 aircraft which involved a full conversion of the aircraft to a Class C freighter.2. Nose Landing Gear Gravel Deflector3. Cabin Safety Equipment STCMy contribution to these projects is summarized below:- Utlilzed SolidWorks to design a halon bottle support and halon tubing routing to 4 nozzles - Created engineering drawings to install the system- Liaised with the machinists in the manufacture and installation of this system (create DCN)- Liaised between ATR and a third party engineering firm to produce structural substantiations for the halon bottle installation design- Participated in test flights for testing of the halon suppression and detection systemAside from this major project, I perform a variety of engineering duties such as:- Design Certificaiton Plans (FAR, CAR, EASA)- Issue DCNs to drawings- Survey aircraft structure- Design/certify modifications to interdependent avionics/mechanical kinematic systems.- Manage aircraft repairs during maintenance checks- Recommend and ensure accuracy of repairs as per the manufacturer structural repair manual (SRM)- Write and revise ICA documents (IPC, ICA, MMS, MDL)- Source materials for certain designs with use of the MMPDS- Write structural substantiation reportsWith regards to aircraft repair, I survey, diagnose and recommend both standard and non-standard acceptable aircraft repairs. Standard repairs can be performed with reference to the aircraft SRM. Mechanics perform these repairs with my oversight.

My duties at DART Aerospace consisted of the following tasks: -Responsible for the development of new designs and modifications from conception to Regulatory approval (FAA or Transport Canada). A typical project would involve developing the design and associated manufacturing drawings in addition to the development of all associated documentation required for regulatory approval by Transport Canada or the FAA including; Airworthiness Compliance Plans, Engineering Stress Analysis, Instructions for continued Airworthiness, Flight Manual Supplements, and Maintenance Manual Supplements. -Member of Mechanical Design Team – Work from conceptual design through certification to final product and receipt of STC.-Detailed working knowledge of the FAR 27 and 29 (CAR/AWM 527 and 529) requirements pertaining to Normal and Transport Category Rotorcraft.-Created Stress Reports using MathCAD to validate Airworthiness requirements outlined in FAR 27/29.-Responsible for creation and editing of Installation Instructions, Instructions for Continued Airworthiness, Airworthiness Compliance Reports, Qualification Reports, Flight Manual Supplements, Maintenance Manual Supplements and Master Document Lists. -Generated Test Plans and Test Reports as part of Airworthiness compliance. -Improved drafting abilities using SolidWorks, simulations, FEA and AutoCAD.-Experience with Bell, Sikorsky, Airbus, Eurocopter and Robinson aircraft.-Trained in DO-160 Environmental Qualification of Aircraft Components

My duties at First Air consisted of the following tasks:-Performed the “Combi Conversion” on two aircraft, a Standard Cargo Door and a Large Cargo door version.-Extensive use and knowledge of SolidWorks (models and drawings) and AutoCAD.-Created installation, assembly and detail drawings of various avionics, sensors, hydraulic and interior structures and systems.-Created a wide range of 3D sheet metal models and drawings, such as interior liners, bulkheads, cover plates, attach brackets. -Acted as the liaison Engineer between production workers and other design Engineers.-Creation of a bill of materials for part, assembly and installation drawings.-Responsible for managing, documenting and publishing hundreds MRBs/ADCNs/ECNs related to the project.-Performed basic stress analysis and calculations of created sheet metal parts.-Generated fleet-wide repair service bulletins.-Sourced fastener and material specifications (MS, BAS, AN, NAS, HI-LOK, Cherrymax, AL 2024-T3, AL 6061-T6, AL 7075-T6).-Maintained and allocated all drawings pertaining to production including design of a 800 part drawing tree.-Acted as the focal point between First Air and various outside organizations.-Participated in test flight and Transport Canada certification procedures.-Experience with HERC, Boeing 767, 737, 727-200, ATR72-212, ATR42.
