  design is 
  there such necessary importance 
  assigned to structural weight. The efficient 
  aircraft and powerplant structure is the zenith 
  of highly reined rknimum weight design. 
  in  order to obtain the required service life from 
  his aircraft, 
  the Naval Aviator must undet- 
  stand, appreciate, and observe the operating 
  strength limitations. 
  Failure to do so will 
  incur excessive maintenance costs and a high 
  incidence of failure during the service life of 
  an aircraft.
