A pilot preparing for an add-on multi-engine rating checkride describes significant difficulty executing stable instrument approaches in a Piper PA-30 Twin Comanche, citing loss of IFR procedural fluency after an extended period without instrument flying and an inability to establish proper configuration and energy management during LPV approaches. The pilot reports dropping gear at the FAF but failing to achieve a stabilized profile, indicating a breakdown in the standard instrument approach sequence rather than a failure of basic airmanship. The post also flags a persistent inability to demonstrate positive single-engine climb performance, which is a core checkride standard and a genuine operational limitation of the PA-30 airframe under certain conditions.
The procedural disconnect described here is a well-documented phenomenon among pilots returning to instrument flying after a lapse — sometimes called "rusty IFR" — and it compounds sharply when a new airframe is introduced simultaneously. The PA-30 Twin Comanche is a capable but demanding light twin with relatively low thrust-to-weight margin on a single engine, particularly at higher density altitudes, gross weights, or with landing gear or flaps extended. For pilots transitioning from single-engine IFR operations, the cognitive load of managing two engines, monitoring asymmetric failure scenarios, and flying a precise RNAV(GPS) LPV approach simultaneously can saturate working memory, causing the standard flow — GUMPS checks, configuration callouts, stabilized approach criteria — to fragment or collapse. The pilot's description of being "swamped and overwhelmed" is a textbook articulation of task saturation, not a skills deficit per se.
For professional and corporate pilots, this scenario highlights the importance of structured recency management and simulator-based procedure rehearsal before transitioning to a new category or class. Multi-engine add-on training in the Part 61 framework is minimally prescribed — no specific hour requirements exist for the rating itself — which means the depth of preparation is almost entirely dependent on the student and CFI. Pilots adding a multi-engine rating to an existing instrument certificate are expected to demonstrate IFR proficiency to PTS/ACS standards in the multi-engine airplane, yet many approach the add-on without refreshing instrument scan and approach flows first. Separating those two training objectives — restore instrument proficiency in a familiar single first, then transition the multi-engine skills — is a commonly recommended but frequently overlooked sequencing strategy.
The single-engine climb concern raised in the post carries significant operational weight beyond the checkride. The PA-30's published single-engine service ceiling and climb rates are sensitive to density altitude and configuration, and some variants with original engines operate with barely positive single-engine climb margins at sea level under standard conditions. In the real-world operational context of Part 91 or 135 flying, single-engine climb performance dictates whether an OEI missed approach is even viable at a given airport elevation, temperature, and weight — a planning consideration that professional operators address explicitly through performance charts and alternate airport minima analysis. The checkride standard requires demonstrated positive climb, but the broader lesson for professional operators is that light twin performance margins demand meticulous preflight weight-and-balance and performance planning, particularly in mountainous or high-elevation environments where the PA-30 and similar twins offer far less margin than turbine equipment.
The broader trend this post reflects is the growing complexity of the add-on pathway for pilots who earned instrument ratings years earlier under different training cultures and then step into multi-engine operations, sometimes accelerated by career or business aviation goals. As the pilot supply shortage has pushed more operators toward Part 135 single-pilot and light twin operations, the pool of pilots pursuing multi-engine ratings without robust IFR recency has expanded. Flight departments and charter operators evaluating candidates with freshly minted multi-engine ratings should treat instrument recency as a separate and distinct competency from the rating itself, and structured IOE or standardization programs for light twin operations should explicitly address approach procedure discipline, energy management in IMC, and OEI missed approach planning as foundational elements rather than assumed proficiencies.
