C Check
This is performed approximately every 15–21 months or a specific amount of actual Flight Hours (FH) as defined by the manufacturer. This maintenance check is much more extensive than a B Check, as pretty much the whole aircraft is inspected. This check puts the aircraft out of service and until it is completed, the aircraft must not leave the maintenance site. It also requires more space than A and B Checks - usually a hangar at a maintenance base. The time needed to complete such a check is generally 1–2 weeks and the effort involved can require up to 6000 man-hours. The schedule of occurrence has many factors and components as has been described, and thus varies by aircraft category and type.

Famous quotes containing the word check:
“Experience was to be taken as showing that one might get a five-pound note as one got a light for a cigarette; but one had to check the friendly impulse to ask for it in the same way.”
—Henry James (1843–1916)
“cried as he died, fearing at last the spheres’
Last sound, the world going out without a breath:
Too proud to cry, too frail to check the tears,
And caught between two nights, blindness and death.”
—Dylan Thomas (1914–1953)
