Beechcraft Bonanza A36 – Battery Shelf Redesign

Perform all engineering tasks for the design and structural substantiation of a redesigned battery shelf for Beechcraft Bonanza A36.  A significantly larger battery was required to cold start the turboprop aircraft.

Aviation Technologies, Inc.

Services Performed:
PEI provided design, analysis, and DER approval to support the redesign of the battery shelf 

Structural Analysis and  FAA DER Approval:

  • Generate system level finite element models, baseline and modified
  • Modeling of battery to determine center of gravity and tie-down locations
  • Quasi-Static analysis with limit maneuver loads 
  • Global Equivalency and Detailed Stress analysis, including mechanical joints (bolted and riveted)
  • FAA DER review and approval
  • Generation of FAA Form 8110-3 for approval of modifications

Engineering Design:

  • Conducted site survey to measure and document Beechcraft Bonanza A36 battery compartment
  • Modeled local aircraft structure in the vicinity of the current battery shelf
  • Designed preliminary enlarged battery shelf and aircraft reinforcements required for higher loading
  • After structural evaluation, completed detail design of new battery shelf and reinforcing structures
  • Conducted Design Reviews with Aviation Technologies, Inc. representatives
  • Generated all detail part, assembly, and installation drawings
