The airworthiness directive

Compliance is required on or before August 31, 1971, unless already accomplished.
To prevent possible failure of the Dunlop compressed air bottles used in the emergency landing gear extension systems, inspect the compressed air bottle (P/N AH.7360 or AC.11038) installed in the air bottle assembly (P/N AH.8512) located under the pilot's seat. If the air bottle was manufactured before January 1, 1959, replace the air bottle assembly with a serviceable assembly of the same part number which incorporates an air bottle (P/N AH.7360 or AC.11038) manufactured on or after January 1, 1959. The date of manufacture is etched on the collar of the bottle.
