A. Procedure
(1) Make sure that the identification of the cause of the vibration is correct (Ref. TSM TASK 05-50-00-810-801).
(2) If the flight crew have reported vibrations in the center cabin area, do the fault isolation.
4. Fault Isolation(1) Make sure that the identification of the cause of the vibration is correct (Ref. TSM TASK 05-50-00-810-801).
(2) If the flight crew have reported vibrations in the center cabin area, do the fault isolation.

A. Do a visual inspection of the Aerodynamic Panel-Edge Seals
(1) If the seals are damaged or missing, you must replace the seals AMM 53-25-11-000-001 and AMM 53-25-11-400-001 or AMM 53-35-11-000-001 and AMM 53-35-11-400-001.
(2) If you cannot see damage to the seals, but the vibration continues during the subsequent flight:
(5) Do step (4) again after each subsequent flight, until you find the panel with the vibration.
(6) When you find the panel with the vibration, replace the applicable seals AMM 53-25-11-000-001 and AMM 53-25-11-400-001 or AMM 53-35-11-000-001 and AMM 53-35-11-400-001.
(1) If the seals are damaged or missing, you must replace the seals AMM 53-25-11-000-001 and AMM 53-25-11-400-001 or AMM 53-35-11-000-001 and AMM 53-35-11-400-001.
(2) If you cannot see damage to the seals, but the vibration continues during the subsequent flight:
- Temporarily install the high speed tape Adhesive Film Tape-- Aluminium Foil - (Material No.05RAB9) on the panel edges SRM 533511 and SRM 534512.
NOTE: Use sufficient high speed tape to apply to the panel seals and panel edges.
(4) If there is no vibration during the subsequent flight, remove the high speed tape from one panel. (5) Do step (4) again after each subsequent flight, until you find the panel with the vibration.
(6) When you find the panel with the vibration, replace the applicable seals AMM 53-25-11-000-001 and AMM 53-25-11-400-001 or AMM 53-35-11-000-001 and AMM 53-35-11-400-001.
NOTE: Replace the seals at the next maintenance opportunity if the seal is damaged.
