A D Check happens every six to ten years and basically, a crew dismantles the entire aircraft and puts it back together again over a month or so. • D-check (ди-чек) — самая тяжёлая форма обслуживания самолёта. Эта проверка происходит примерно раз в 12 лет и длится 30-40 дней. Во время неё проверяется весь самолёт, все его узлы и детали. Узлы, выработавшие ресурс или не прошедшие проверку, подлежат замене. Эта проверка воздушного судна требует ещё больше места и времени, чем все другие, и выполняется на соответствующей технической базе.  wikipedia.org • The D check, sometimes known as a "heavy maintenance visit" (HMV), is by far the most comprehensive and demanding check for an airplane. This check occurs approximately every 6-10 years. It is a check that more or less takes the entire airplane apart for inspection and overhaul. Even the paint may need to be completely removed for complete inspection of the fuselage metal skin. Such a check can generally take up to 50,000 man-hours, and 2 months to complete depending on the number of technicians involved. It also requires the most space of all maintenance checks, and as such must be performed at a suitable maintenance base. The requirements and the tremendous effort involved in this maintenance check make it by far the most expensive, with total costs for a single D check in the million-dollar range. 'More) |
