INSPECTION AFTER FLIGHT IN SEVERE AIR TURBULENCE
OR WITH SEVERE MANEUVERS
INSPECTION / CHECK
1. GENERAL
This inspection is implemented :
- upon request of the pilot in the flight report,
- after observation during a workshop inspection which would tend to indicate that the airplane has been flown in severe air turbulence.
Checks are broken down into two categories, the first described in Paragraph 2.C. "First-level" investigation, the second is implemented as per conditions described in Paragraph 2.D. "Second-level" investigation.
CAUTION : EVEN IF EVIDENCE OF WRINKLES AND WAVINESS ON FUSELAGE OR WING SKINS MAY SEEM MINOR ENOUGH TO BE CONSIDERED AS NEGLIGIBLE, A CAREFUL AND METICULOUS INSPECTION OF THE INTERNAL STRUCTURE COULD REVEAL MAJOR DAMAGE.
2. DETAILED INSPECTION
A. Tools and consumable materials None
B. Preliminary operations
With the airplane on a flat and, if possible, horizontal area, check whether the various components are in their normal configuration.
C. "First-level" investigation
1) Wings
a) Inspect the central structure of the wing. Particularly check for the following on the lower and upper skins :
- wavinesses in the skin level with the spars, between the rivets,
- wavinesses in the panels,
- missing or slack rivets.
b) Carefully inspect the spar via the inspections doors.
c) Visually inspect the attachment brackets in the feed-through structure ; check for any cracks or riveting faults.
