My tribute to Osh '25 and the plane my dad lost in September.

This Reddit post offers a personal rather than a technical or regulatory story, but it touches on themes that resonate deeply within the homebuilt and general aviation community. The author's father spent twenty years building a Zenith CH 601HDS, finally reaching EAA AirVenture Oshkosh with it, only to suffer an engine-out event the following September. The son's tribute—a tattoo commemorating the aircraft and the journey to Oshkosh—captures the emotional weight that experimental aircraft builders and their families invest in these long-term projects, and it stands as a reminder of both the triumphs and risks inherent in homebuilt aviation.

The Zenith 601HDS has a documented history worth noting for pilots and owners in this category. The type, along with its successor variants, has been the subject of NTSB and FAA scrutiny over the years related to in-flight structural and control issues, particularly involving aileron flutter and canopy departures at certain speeds, which led Zenith to issue modifications and service bulletins. While the article doesn't specify the cause of the engine-out event, the fact that it resulted in a survivable outcome—allowing for continued reflection and tribute rather than tragedy—speaks to the value of the emergency training and glide-planning that builders and pilots of experimental aircraft are strongly encouraged to internalize. Engine failures in single-engine homebuilts, often powered by auto-conversion or lower-time experimental powerplants, remain statistically more frequent than in certificated production aircraft, a fact the FAA and EAA have highlighted in safety campaigns aimed at first-time builders and pilots transitioning into the E-AB (Experimental Amateur-Built) category.

For working pilots—whether flying for the airlines, in Part 135 charter, or business aviation—this story is a useful cultural touchpoint rather than a direct operational lesson. Many professional pilots got their start, or maintain their GA currency and passion, through homebuilt projects and EAA involvement. Oshkosh itself functions as an annual pilgrimage that bridges every corner of aviation, from airline captains to weekend builders, and stories like this reinforce why the show retains such significance: it is not just a trade event but a communal celebration of the sweat equity and risk tolerance that underpins general aviation's experimental segment. The engine-out incident also serves as an informal case study in the importance of thorough pre-flight risk assessment and continued proficiency training, values equally applicable to turbine operations even if the failure modes differ substantially.

More broadly, this post reflects a persistent trend in aviation media and online communities: the increasing use of personal storytelling and social platforms to document both the achievements and hazards of amateur-built aircraft ownership. As the homebuilt fleet ages and more aircraft accumulate flight hours, incidents involving legacy designs like the Zenith 601 will likely continue to surface in NTSB databases and online forums alike, feeding into ongoing discussions about maintenance vigilance, powerplant reliability, and builder support networks. For an industry increasingly focused on safety culture at every level—from Part 121 SMS programs down to individual EAA chapter safety seminars—this small, human story underscores that the emotional investment in flying, and the acceptance of its risks, remains a constant across every segment of the profession.
