When is an aircraft equipped for "Day VFR Only" operation required to have its altimeter inspected according to 14 CFR 43, Appendix E?

For an aircraft equipped for "Day VFR Only" operation, there is no requirement for the altimeter to be inspected under 14 CFR 43, Appendix E. The regulations specify that only aircraft that operate under IFR (Instrument Flight Rules) or are used for controlled flight into instrument meteorological conditions (IMC) are subject to regular altimeter inspections. In this context, "Day VFR Only" indicates that the aircraft is not equipped for, nor intended for, IFR operations, and therefore the altimeter does not need to adhere to the same inspection requirements as those aircraft that are. This distinction is critical in understanding the maintenance and inspection schedules set forth by the regulations.
