Professional scope: This edition is written for working accountants and finance teams. It explains how the issue appears in ledgers, processes, controls and financial reporting—not how to answer an examination question.
The accounting question

Practical corporate example
An aircraft includes an engine with a shorter useful life than the airframe. When the engine is replaced, the new engine is capitalised and the carrying amount of the old engine is derecognised, even if the original invoice did not separately identify that amount and estimation is required.
Typical accounting pattern
ReplacementDr New component; Dr Accumulated depreciation and loss if any / Cr Old component cost and Vendor/Bank
DepreciationDr Depreciation expense / Cr Accumulated depreciation
The exact entry depends on the entity’s facts, chart of accounts and applicable reporting framework. Review the complete standard and professional advice where necessary.
