78.74 in.) as perpendicular as possible to the skin (Refer to Figure
1008).
(3) Focus the camera during the inspection as necessary.
(4) Auto-adjust the camera every 2-3 minutes minimum of continuous inspection
following the requirements in paragraph 6.F.
NOTE: In case of findings auto-adjust the camera on the indication when
necessary to help indication bordering. Then point the camera to
T.E. for camera calibration obeying paragraph 6.F.
(5) You have only 20 minutes to inspect the elevator. If you need more time to
complete the inspection, repeat the steps from paragraph 5.G.
(6) You must do an inspection of the two elevator panels.

F. For all METHODS
(1) Trapped water inside the honeycomb core will be identified by darker
indications when compared with the adjacent area. Refer to Figure 1010 to
identify different thermographic indications.
CAUTION: SPECIAL CARE MUST BE TAKEN WITH INDICATIONS THAT MAY APPEAR ON THE
SCREEN WHICH ARE CAUSED BY:
- SURFACE REFLECTIONS OF HEAT SOURCES SUCH AS LIGHTNING, AIR
CONDITIONING, ETC.
- HONEYCOMB FILLER AROUND THE FASTENERS (25 mm (1 in.) dia.)
- CORE SPLICES (MAINLY IN THE RIB END)
- GEOMETRIC INDICATIONS (REPAIRS)
(2) In case of findings that may be partially occluded by a lightning strip:
- Do an X-Ray inspection of this area or
- Remove the lightning strip and do the thermographic inspection again to
find full damage size.
(3) All thermographic indications with a regular shape or located at the end
of a rib, shall be checked by a tap test, refer to Chapter 51-10-03 Page
Block 501 to avoid misinterpretation of structural changes such as
repairs, core splices, etc.
(4) To make marks on areas identified as trapped water:
- Put the portable monitor near the inspection area
- Refer to the indication on the screen
- The inspector will make marks on the edge of the darker areas to
identify trapped water while the assistant keeps the image.
8. ACCEPTANCE CRITERIA
A. All dark indications which cannot be identified as geometric changes such as
ribs, hoisting points, fasteners, core splice, honeycomb filler, etc., surface
irregularities, foreign materials or heat/cold source reflections on the
surface must be considered to be water indications.
B. Make a full-scale map of the findings on a plastic foil, including distance or
references to the elevator front spar rivet rows and other geometrical
references such as ribs, lightning protection plates, fastener numbering, etc.
to help the elevator repairs.
