Unsafe Condition
The Aircraft Maintenance Manual (AMM) for PC-6 B2-H2 and B2-H4 models lacks Chapter 04 in the Airworthiness Limitations Section (ALS). For other PC-6 models, no ALS is included in the AMM. The absence of these documents, which contain Mandatory Continuing Airworthiness Information (MCAI), constitutes an unsafe condition.
