Back to: "W"wing spar
- Definição1
- Principal spanwise member of wing, in traditional or light aircraft usually isolated but in modern stressed-skin wing forming one face of wing box which itself behaves as a spar. Always extends full available depth, unlike stringers. In slender delta built perpendicular to longitudinal axis, thus in such wings there are many spars which terminate not at tip but at points along leading edge.

- Contexto
- One example is the crash of Chalks Ocean Airways Flight 101 in December 2005 off the coast of Miami, FL. Initial evidence indicated that the right wing had separated in flight. Within days, the NTSB had identified fatigue damage in metallic structural components in the right wing (Figure III-9-25) with corresponding damage in the structure of the left wing. As shown in Figure III-9-25, an unaided visual inspection of the wing spar cap reveals beach marks, which is evidence widely accepted to indicate fatigue failure. As a result of this established analysis, the wing spar cap was identified within days of the accident as a critical component in the investigation.
